    Motor Knock

    U sure transom is not rotten???? Who dropped it? How old is boat? Wood or synthetic transom core? Why didn't mechanics examine or call u to examine damaged transom assembly(s) and CORROSION? If stringer damaged, perhaps alignment is out as well??? Sounds like a salt water stored boat due t...

    Something is wrong with "Home made special tools"

    If my memory servers me correctly, u will need a good slide hammer with claws that fit inside gimbal bearing if your want to pull gimbal bearing. I assume bearing is "rough???" Google "Mercruiser outdrive removal tools" may help. Good luck! I also believe there is a turnbuckle type tool that...

    Water Pump Question - Alpha 1 w/Closed Cooling

    If motor has been used extensively in saltwater, I have been told that internal rust may cause an issue with clogging heat exchangers. I have 2 crank pumps on Bravos. They work great, so far. But, I suspect that for Alphas, you'd have to replumb water input.

    Possibly seized motor?

    Years ago, I learned the hard way not to rely on that bolt to turn engine, unless plugs are out (no compression) and then I'd pray.

    Possibly seized motor?

    I'd use a special oil pump primer distributor tool and drill to pressurize or force oil to journals and pushrods, before I would do anything. Make sure starter isn't froze up and you have GOOD WIRING CONNECTIONS and strong BATTERY.

    No water out transom or exhaust

    I suspect something malfunctioning in water pickup. However, perhaps this has been discussed, but is boat salt water used/stored? It is my understanding that fresh water boat risers and exhaust manifolds don't clog up with rusts as frequent as salt water ones do. I have replaced several salt...

    Why an increase in engine horsepower will hurt your ‘holeshot’, acceleration and midrange cruising.

    Good explanation!!! And, most people do not factor in safety with too much HP than the boat can handle. I have personally witnessed careless show-off captains submarining in dangerous seas.

    Engine failure?

    BT is correct. Too hot. Sounds like a fresh water boat. How old? I suspect old or worn out impeller and maybe clogged risers or you sucked a plastic bag around water pickup. I did that once and temp went through the roof! I now have audio alarms in addition to gauges . Pull plugs and pray no...

    What is this gel-like substance in my carb? Mercruiser 3.0L Alpha 1

    Good luck totally eliminating all contaminates from carburetors. I have experiences some success by draining fuel/water separator every couple of weeks during boating season and keeping tanks full. Yet, condensation seems to always win and end up inside carbs.. I run the cheapest gas that I can...

    plug is a plug?

    some of the plugs seat too deep and may hit pistons. Just use old plug and measure, just to be sure. I believe MR43LTS will work fine....
