    1990 Chaparral 1900 SL

    I had an old Arrow Glass 21' boat. The back seat upright was part of a bulkhead that mad getting tot he rear of the engine a pain. There was a "dog house" engine cover that exposed the front of the engine pretty well. I ended up removing the bulkhead and replacing it with multiple screw in panels. I only had to take it apart a couple of times but was worth it when I had to replace a starter.

    Chap Website Update

    I just did a quick check. Not even a cuddy cabin available on anything. The few I did check in detail (347 SSX for example) are pretty nice looking boats. But we are express cruiser boaters. Maybe by the time I'm ready to upgrade, they'll have an offering to look at.
  3. I have 4 fenders, 8" by 20 inch. I have one that is 6" diameter. I think I have another two 8" x 20" in the garage.

    time to move up... engine(s) question

    OK, so I did a couple of runs and this is what I found. I forgot to grab the paper I wrote down the numbers on, but I think I remember. Sitting in the slip, lets call this the reference, the radar dome is about level. Maybe, 1 degree down. Maybe. Hard to get super accurate as I was standing on the transom seat back and reaching up. Placing level on the ledge at the base of the gauge cluster, I had a reading of -5 degrees. That is, there was a slope of the shelf I set the phone on such that it dropped down 5 degrees towards the bow. At slightly above idle, say 1000 rpm, my speed is about 5 mph. No change in level at the helm. At 2400, I am doing about 18 to 20 mph. Level is reading plus 2 degrees. So what that is saying, is the bow rise is about 7 degrees. Note that at this speed, I am not on plane. I can lower trim tabs all the way and drop bow about 1- 2 degrees so that the level is reading about 0 degrees. Getting the rpms up to 3200 to 3400 rpm gets me up on plane and bow drops back down such that the level reads about -4 degrees. Speed is about 26-28 mph. I can drop revs back a few hundred rpm and hull will stay up on plane. That means that the bow is riding about 1 degree up. Based on my reading of the radar dome, I would say having it set at the angle it is set at is pretty much perfect. Increasing speed to 32 mph doesn't effect the attitude of the hull. Again, dropping trim tabs all the way down will lower bow about 2 degrees. So I can pretty much get same attitude of the hull at speed as it is when sitting still. But, I notice that dropping the tabs all the way did add more load to the engines and speed drops. I've run with full throttle. Engine revs got up into mid to high 4000s. Speed got up to 42., again no real change in attitude of the boat, so still runs pretty level. I ended up with an alarm after a few minutes which cut the full throttle test short. I shut it down and restarted and alarm went away. A friend hooked up scanner and found out it was knock sensor. I guess I need to look up the causes and potential corrections. Next season. Boat will be out of the water in two weeks for winter storage.

    I'll mount my iPhone on the inside of the radar arch or at the helm on the side. Under the Utilities feature there is a level app. Works alright. I'll take a look at various speeds and what the angle of boat is at those speeds.

    Yep, meant I/O. You can see in my signature photo that mine is only tilted a little. As I said, I don't have a lot of bow rise on plane. Maybe 5 to 7 degrees. I'll have to use the level function next time im out.

    time to move up... engine(s) question

    So this weekend we were out and I was paying more attention to the express cruisers in the area. There were several that were cruising along with bow high in the air. A tilted radome would be necessary on those. There were a few that seemed to ride level. Now, here is another part of the observations. We took a ride from our marina down to city of Buffalo, probably a good 12 mile trip. My Sig 300 likes to get up on plane and cruise around 3200 rpm to 3800 rpm. Speed is around 28-30 mph. I can run down to about 2800 rpm and hang on to plane at 24 mph but I usually will drop trim tabs down to lower bow. During this range of operation my boat is pretty flat. Some bow rise, but I can sit in the helm seat and see through windshield and pilot with no problems. But I noticed that I would come up on other express cruisers pretty fast. I was always passing them. We must have passed a half dozen cruisers and a few other smaller boats, all of which seemed to be in a hurry to go somewhere. So now I am wondering if the drivers of those boats aren't fully up on plane, not using trim of outdrive or trim tabs? I had no way to stop and ask how they were equipped. Or maybe I just like speed and I am going fast enough to keep my hull up on the water and making use of the extended V plane design. Hmmm? In short, maybe its not the difference between V-drives and outboards, but how the craft is being piloted?
  8. Well, the biggest screw up NY had done was to allow excavation of material from what was Strawberry Island back in early 1900s. There used to be a 200 acre island that was in the middle of the river with several smaller islands. The DEC and Army Corp of Engineers have been rebuilding the shallows and have made what is left of the island, currently about 5 acres, off limits. Some wild life has returned. There are a bald eagle pair on island, and sightings of river otters. Game fish have been using the grassy shallow areas too. But for all the good stuff recently, there is still tons to do. Maybe they can clean up some of the industrial sites and make more green space for nature.
  9. Buffalo News wants me to subscribe, but I think I have read that article reprinted elsewhere. When we had our old boat we used to go there once and a while. With the Sig 300, just twice so far in three years. Yes, I anchor. There are usually four to five rows of boats that anchor. The closest row ends up with the stern of our boats about 30 or 40 feet from the grass. Its pretty shallow area. Anywhere from about 2' deep to about 4' deep. If done right, a couple of mid size boats will anchor about half way between shore and the drop off. Small boats will tie off on shallow side then us express cruisers will anchor off on deeper end. Its shallow enough to jump out of the boat and walk the boat and manually set the anchor. Most have a T bar or screw for aft anchor. Basically everyone anchors and walks around. No one screws with the grassy area itself. But I understand from environmentalist that there is a "corridor" where animals will avoid a certain distance from humans. That was the push to ban everyone. But I think if there is a natural reef, and they retain the shallow area to anchor, it can be a win win.

    This is for Hatem

    Funny story about my waterproof flashlight. Last season early in the summer my daughter had asked me to hold her bag that she was taking up to the shower. It was dark out and I had this decent tactical LED flashlight. Super bright, probably too bright for just bumming around on the dock. Anyway, she had some special face scrub on the top of the bag (16 year old) and it fell off and into the water. Well current starts taking it down river. I run to the end of the dock with flashlight and reach down to grab it. Just then the flashlight slips out ad drops into the water. I watched it as it slowly twisted with its bright beam shining up towards me like Jack Dawson to Rose. It hit bottom 15' down and face scrub made its way to Niagara Falls I could see the glow of the light the next night before the battery finally succumbed to time. It was an aluminum no magnet would pick it up. I was bummed, and my daughter was mad at me all weekend. Sigh.

    Survey/Pre purchase inspection in the Baltimore area.

    Go pro on a selfie stick is great for inspecting. On my go pro I can transmit the images to my phone. Start and stop recording from phone too. And works underwater if boat is in the water.

    Mercruiser Alignment

    So I have had one drive off already. I cracked the casing on the lower oil drain plug trying to get it out to change oil. So I had a new lower put in. I took the opportunity to change bellows, gimbal bearing, trim position sender and limit switch. I also changed lower shift cable. I had done all the work at the marina (they have some decent work racks) but didn't have alignment tool. I had a tech come over from the shop and check but I wasn't there. The note said everything was OK. This was beginning of last season. Everything was fine all year. I am going to service the other drive this fall. I am already anticipating having difficulty getting lower plug out (boat had seen saltwater at some point) so plan on taking whole lower drive to a Mercruiser shop on Grand Island. The guy there does great work in my opinion. But I am pretty mechanically inclined and able to understand the mechanics pretty well on these. Back in my younger years as an engineer, I wrote some alignment procedures for pumps. Most of them use flexible rubber biscuit type couplings, or more rigid spline couplings. I've also worked on high speed turbomachinery that uses rigid disc couplings (50,000 rpm). SO I was thinking about the procedures I used to use and compare to Mercruiser's manual. I was thinking about how to adjust the motor horizontally if the alignment was off. On the machinery I worked on you could shim in all directions to get co-axial and perpendicularity perfect. We usually had a spec of 0.001" allowable on the higher speed stuff. as much as 3 to 5 thou on flexible couplings. The machinery runs 24/7 365 so good alignment was critical for reliability. So in summary, it is much more curiosity and trying to understand the machinery to another level. I do 99% of my own work when I can. I find have the engineering background and knowledge of the equipment much more useful than relying on some of the techs the marina has. I am only impressed with a couple of the techs there but getting them specifically assigned is difficult as they are usually in high demand. .

    Mercruiser Alignment

    So I've read various posts about performing the alignment with the alignment tool. They all talk about raising or lowering the front the of the engine. What if the grease method on end of shaft indicates off side to side? Is this possible? How is the rear of the engine indexed to the transom assembly? I am curious. I may need to see if marina shop has an assembly out that I can look at easier than crawling into engine compartment on my boat. Between the batteries and water tank, its almost impossible to get past the front of the engine.

    Vibration - Hard to tell

    So we haven't had the boat out of the slip much this year. In fact, it sat in slip so long I think I had sea grass growing off the underside. Anyway, the last couple of outings I think I feel a vibration. Anyway, it doesn't feel as smooth as what I could recall last year. When I start the engines and am idle, I can sort of feel or hear a low frequency vibration when I go below into the mid berth. I never really go down there, so I am not sure if it was always there. But, when I get out into the water, I can feel/hear that same frequency vibration in the hull. I've restored classic cars and its not unlike a bad u-joint type of vibration. Seems to be the same out of both port and starboard engine. Adding turns or varying the RPMs while out cruising doesn't seem to change the amplitude, though frequency changes (gets higher with rpms, like a u-joint) but Its sort of always there. Weird thing is that its both engines. But my Starboard engine had new bellows and gimbal bearing replaced last season. So I'd expect one to be worse than the other. Motors sound great, and I haven't noticed any loss of power. Could be normal vibration and noise that I never really noticed before. But with this being our third season I am getting more aware of the various noises and such from the boat. Any thoughts? I will probably pull drives and check alignment in the fall. I'll get bellows and bearing changed on port engine too. But I am wondering if there is something else I should be looking for? Anything else to do some diagnostics?

    time to move up... engine(s) question

    I don't know about V-drives pushing engines back. All outdrives have engines right up against the transom. On the Sea Ray at our dock that has out drives, there has to be at least 6" more between the transom and engine than on my Sig 300. Also, V-drives place the transmission towards the center, so should be better weight distribution. Or am I missing something?
