  1. Here is my current "new part's" list.. any suggestions on anything that "absolutely" needs to be replaced at 550 hours? At this point I'm so deep.. where the mechanic isn't asking a whole lot of money to swap old parts for new.. Complete Long Block Exhaust Flappers Distributor, Coil and Ignition Belt Head Bolt (1 of 2) Head Bolt (2 of 2) Head Gasket Valve Cover Gasket Spark Plug Cable Kit and new Sparks Exhaust Gasket Fuel Filter Intake Gasket Water Pump Theromostat Alpha 1 - 0L943360 Impeller repair kit Alpha 1 Gen 2 Transom Bellows Repair/Reseal Kit Trim Sender Unit (mine is busted)
  2. How did that turn out for you? Kinda excited to see the Long block getting dropped off today - on a big truck!
  3. Well guys.. its kept getting worse and worse.. We took apart the heads. The low compression side had a huge gap in the head gasket (about 1/2'") between the cylinders.. that was the easy part. The worse - we had fire pitting on the block. To the point were neither of us where comfortable slapping a new head gasket down and going about. Also, the opposite head had a pretty noticeable crack on one of the water ports.. the giant intake gasket might of sealed it up.. who knows! After reaching out to a few shops to get the block and heads straightened out.. we decided to just replaced with a long block from Mercury. (3500 to deck the block and heads vs 4100 next day delivery from Mercury). This saved us from weeks (maybe a month) to just days. Tall order? Yes.. but at least it comes with a warranty! Next step is to return some parts and see who wants to by my old assembly! lol. I'll keep anyone in the loop who is interested about the process... block should get here today . Okay got to get back to work and figure out how to pay my credit card off, lol.
  4. Update - between 3 and 5 .. head gasket was gone! Its not great news.. but at least progress is being made!
  5. I like this idea and did something like it on my car restoration project.. but for this particular instance.. I want to keep as OEM as possible.

  7. First round of parts ordered. Saved about $150 bucks by sourcing thru NuWave Marina (plus I get points too!) I really focused on cooling - since that seems to be what caused the head gasket to go in the first place, right? Name Part Number Quantity Cost Head Bolt (1 of 2) 10-119671 4 13.17 Head Bolt (2 of 2) 10-11966 14 12.78 Head Gasket 27-75611001 2 47.99 Valve Cover Gasket 8M0150306 2 22.06 Spark Cable Kit 816761Q17 1 66.99 Exhaust Gasket 33395 2 11.02 Fuel Filter 35-802893Q 1 19.99 Intake Gasket Kit 807473A1 1 56.75 Water Pump Assembly 46-8M0113734 1 144.64 Theromostat 8M0109441 1 30.61 Water pump Impeller kit 47-8M0100526 1 49.78 Tear down by the shop began Monday.. waiting on results before I replace with brand new heads (aprox $1200 shipped in 2 days) or send of the old heads to be machined (no idea how much this would cost or take time) I see the recommendation to replace the distributor / ignition assembly / coil ($427) starter ($233) and belt ($96 - wow really?) which would take priority? Sounds like the starter right? I have no intentions of just replacing random parts.. but since the guys are already tearing have the engine down, might as well utilize their time best. Thankfully work has been crazy and overtime is helping pay these repair bills!
  8. Thats a great list! Thank you for sharing.. Not sure about the water pump, as I'm the third owner but since its already being pulled.. I cant imagine why not!
  9. Finally got a shop on board. Supposed to pull the boat out and start tearing her apart.. Given shes almost 20 years old.. 550 hours.. is there anything I should maintain on the Alpha 1 (Gen 2) outboard? Might as will pull it off (6 bolts and a clip). So far - the only thing on my list is to replace the exterior exhaust bellow (looks pretty old).. possibly repaint and resticker. Any suggestions?

    Switch Covers

    I purchased my covers from this seller on ebay. They ship with switches too, however you can pop the covers and use on your existing. Pretty cool if you want customization (I did for subwoofer and tower amplifiers, etc) https://www.ebay.com/itm/BLUE-Laser-Etched-LED-Rocker-Switch-5-PIN-Dual-Light-20A-12V-ON-OFF-SPEAKER/323700666685?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

    Switch Covers

    Nice! That tool will make it much easier than a small flat head screw driver!
  12. Quick update. Pulled the valve on the side with the low compression. Every valve has this slight “looseness” from left to right (parallel to the length side of the engine) expect for the 4th valve (as in video below) on chamber 5 (my modest compression reading) Edit. The spring is compressed on that valve.. which I’m why I’m assuming no looseness.. However - I did put the valve cover back on, crank the engine (not start) took cover off to re-examine.. and notice the same spring was still compressed.. along with a spring on chamber 1. blah!! Going to talk to a new shop tomorrow https://ibb.co/V3Mc5Bx
  13. Curious - what is the process of inspecting the valves? Remove the valve covers and observe the springs / rockers? In other words.. is a stuck valve clearly obvious based on a visual inspecton of removing the cover only? (I don't have much experience with head work.. ) Thank you
  14. here is an absolute crazy idea.. instead of checking all the valves and getting the heads both machined - which could take weeks.. (no idea how much it will cost) and kinda guess at the problem.. Would it make since to just replace both heads outright? It looks like Mercury sells compete assemblies (8M0115137).. That way I can literally just bolt them on with new gaskets. and get back on the water. (Same with the distributor too). Maybe im just loosing momentum and thinking crazy??? lol
  15. Well the results are in! Too bad its not in house favor... Cylinder 2 - 160 Cylinder 4 - 155 Cylinder 6 - 154 Cylinder 8 - 154 Cylinder 1 - 160 Cylinder 3 - 45 Cylinder 5 - 41 Cylinder 7 - 175 For those who dont know.. small contribution to the forum... Cylinders 2,4,6,8 are the left side if you're looking at the engine (starboard) - Cylinders 1,3,5,7 are the right side again. Looking at the engine (port) side (which is where I found the broken exhaust flapper) Good news - no hydrolock. Mystery - why is cylinder 7 so high? He checked it several times too.. And also think its odd that the engine sounds perfect at idle and low RPMs? Before going about replacing both gaskets / checking the heads.. is there anything else we should look at? Like valves?? If it was overheated - Im assuming I would hear an alarm right? (we hear the alarm's test beep every time the ignition is turned on)
  16. Finally paid somebody half down to pull a compression test on Thursday. Picking up new spark plugs tomorrow (might as well swapp them out if your pull'n them)
  17. yeppers! Will do - going to pull the bellow between the stern "y-pipe" and the prop inlet. Order a replacement too.
  18. Update - Still waiting on a mechanic.. and its driving me crazy! So I have done a few things since the request.. hopefully they can get out there next week for a compression test and a quick drive. 1) Update the propeller https://propshopinc.com/14x17rh-4-blade-quicksilver-nemesis-propeller-8m0055534/ . That was a super easy swap (keep in mind I'm a new boater..) 2) Greased up the three grease fittings with Quicksilver per recommendation 3) Took out for a drive yesterday - noise still there.. anchored and enjoyed the sun for a few hours.. limped slowly back home. 4) Today - I took off the exhaust bellows at the elbow.. check out what I found... Starboard flapper missing!!!! Port looked "okay" but pretty old. Went ahead and ordered new OEM flappers. Question.. Im assuming the missing piece of the flapper is downstream of the exhaust? It appears to be constructed of metal, coated with rubber. I really doubt the exhaust can "pass the stone" (ouch, lol) and the flapper is liking in the bellow between the transom and the outboard drive? I pushed my inspection camera down the y-pipe and didst see anything.. infact it looked really clean in there! https://i.ibb.co/Jxcdm7K/z4.jpg https://i.ibb.co/DWCw2xv/z1.jpg https://i.ibb.co/ypnsSV7/z2.jpg https://i.ibb.co/G9B3cGH/z3.jpg Im assuming the exhaust passes only thru the lower hose, right? Circled in red? If thats the case - maybe its in there? https://i.ibb.co/rs28Ry3/Capture.png
  19. Decided to go this route - based on costumer service rep and wanting acceleration Paired with 835257Q1 hub. Well see how it works!
  20. FYI I sent a note to Mercury.. regarding 48-8M0084495 SPITFIRE 14X19RH This seems pretty great for Texas and the acceleration Im looking for.. not to mention - its on sale!
  21. Great - I was looking for somrthing with a lower pitch.. The Spitfire 19" 48-8M0084495 has a note: The high performance blade design is not recommended for Alpha One drives with a 1.47 ratio Hmm wonder why? I have the 1.47 ratio Alpha One (Gen 2)
  22. Greetings - My boat is currently going under repair.. while I have the downtime - I would like to replace my prop (its pretty overdue).. I believe we have a 48-834854A45 Alpha 4 prop (2001 Chap 220 SSI Mericruiser 5.7 + Alpha One).. however the stamp is pretty warn down - and most, if not all.. is showing the prop discontinued and out-of-stock. Does anyone offer any recommendations? We do like watersports over top end..
  23. Finally found a marine mechanic today! Crazy how busy everyone is.. im guessing COVID is pushing more people to the water.. Im going to run a compression test sometime in the next few days - while waiting for the mechanic to free up. Keep fingers crossed.
  24. Video defiantly exaggerates the movement.. It really closer to 1/8" in a single direction (up / down motion). Luckly I was able to check out the same make / model last night.. He had the exact same movement too (Alpha 1 and same prop)
