  1. You can raise the outdrive all the way up and check the pistons on all sides with a straight edge. A nine inch torpedo level should work very well
  2. This is from the history of the Mercruiser Histroy of the Mercruiser Alpha Sterndrive Beginning in 1983 Mercruiser introduced the R/MR/Alpha 1 series of sterndrive models. These units differed greatly from previous years not only in design but also in that the flywheel housing on the engine changed at this point. This creates one of the big break points customers should be familiar with when inquiring about re-powering older boats. Since the flywheel housing changed from 1982 to 1983, you cannot couple a new engine to a pre-1983 sterndrive unit as the rear engine mount spacing differs on the new engine and therefore will not match to the old style inner transom plate. The other difficulty is that the newer 14 inch flywheel utilize a larger coupler that prevents re-using the old flywheel housing on the new engine. R/MR/Alpha Generation 1 model began in 1983 and ran production through 1990. The Serial Number Range for these models ranged from 6225577 Thru 0D469858 Alpha Generation 2 model was introduced in 1991 and are currently still in production. The Alpha Generation 2 models have been broken into several different Serial Number Ranges as follows: 1991 thru 1995 – 0D469859 Thru 0F679999 1996 thru 1997 – 0F680000 Thru 0K999999 1998 and Up – 0L100040 And Up
  3. I also have the same basic set up. I do initially drain the block and manifolds to remove any sand or grit. If there is a measurable amount I use the flushing connection (motor off) to get all of it out. I then set the 5 gallon bucket of anti freeze with a Y connection. Run the motor on the ears on the hose until it reaches temperature then just swap two valves and suck the anti freeze into the motor making sure I see a complete change of color coming out where it should.
  4. I went from a group 24 to a group 27 battery for my starting battery. Simply cut the forward end of the battery tray. Still clamps down like the original.
  5. With an electric fuel pump it should run (if the fuel pressure is low) as soon as you turn the key to on. You shouldn't have to crank the engine to see if it is pumping with the hose disconnected from the carburetor. So it sounds as though there is no 12 volt feed getting to the fuel pump. You should be able to supply it with a temporary feed to see if it operates. If it does trace back to find the interruption in the feed.
  6. If it was just ventilation you wouldn't have to back to neutral and start again.
  7. If you have another prop try it to see if you get the same results. It is possible that you have a (partially) spun hub on the prop and under certain load conditions the prop slips until you back off of it. I had that same problem on a small outboard motor so to test it, I put three small dabs of epoxy to see if it made a difference. It cleared up the problem. I got a new prop and kept the old one as a spare.
  8. It makes a huge difference if it is a fresh water or salt water boat. The salt really shortens the life of things like manifolds. Closed and open cooling systems also make a difference. I personally look for something with less hours on it and fresh water use.
  9. Curt that was a great way to trouble shoot the cooling system. I also pull the drain plugs on the block to make sure no sand or debris is blocking the passageways.
  10. Can the original engine be rebuilt?
  11. Try using a spray bottle with gas in it and spray it into the carb when you reach 20 mph and see if it makes any difference. You can also try bypassing the booster pump to see if that gives you the rpms back.
  12. What was the top speed and rpms last year when it was running well. What is your rpm reading now that it is only doing 20 mph
  13. With the Volvo it is just a learning curve. No complaints.
  14. I've owned 4 Sea Rays in the past. Never complained about quality. I thought they were well built. The 21 footer I had for 25 years. Kept in fresh water 6-7 months a year. Never bottom painted. No blisters or concerns. Now have a 235 ssi. Happy with the quality. It is heavy for it's size but rides nicely because of the weight. It is the first Volvo I have owned which has some good features and some not so good features. I like both brands.
  15. If you are in the boat facing aft looking at the crankshaft pulley and it turns clockwise with the engine running markings to the left of the indicator will be (BTDC) before top dead center. If it rotates counter-clockwise the marking to the right will be (BTDC) before top dead center. So if you have two engines and they are counter rotating to each other, the marks will be on opposite sides of the indicator. I hope this helps.
