    Could I have pooched a part of my ignition system?

    If you installed pertronix you no longer have points would use a spark gap tester to test spark strength

    1989 Mastercraft prostar 190

    19 -21 ft with a 5.0 or better yet 5.7 even a stern drive will do very good skiing. Not competition type passes but for a bunch of avid lake lovers its good. I have a 5.0 upgraded with a 4 bbl edlebrock and 4 blade prop for a azz heavy boat it pops up pretty good.

    1989 Mastercraft prostar 190

    I have thought of the same as well. My college age kids are getting good at slaloming and I want to support it. We have a 21 ft sea ray 200 sport that is great bulls like a bull but the wake is huge so often we use my friends Glastron 185 / 4.3 VP as the wake is smooth for skiing. Ideally I...

    350 mpi rebuild questions

    Thee is very little diff between a truck engine and marine. No you dont need forged pistons as stock is not forged. if you have a low milage core if compression is good swap head gaskets, core plugs, cam, and circ pump and drop it in

    Gear oil leak from stern drive

    Yeah that is a gen 2 replacement drive They have a 3 year no fault warranty that might still be in effect Not all gen 2 drives have a lube bottle but I don’t think 1.75 qts fits on drive alone so look in engine compartment for a lube bottle

    88' Mercruiser 165 harmonic sound

    if it has a greaseable gimbal bearing grease it and see if noise changes. I would also lean towards gimbal bearing Ujoint or drive noise

    1984 Mercruiser 470 Starting Issue

    If it has been sitting any amount of time clean and set dwell on the points. I would do the points service see what that gets you then go into the carb if there are still issues. This assumes you set the idle mixture and idle speed or at least roughed them in. Have you done a compression test

Switch just opens and closes electrically speaking at a given pressure (4 or 7 psi) , sender changes resistance over a pressure range (ohms) to gauge gauge moves based on ohms signal it gets. If you dont have a oil pressure switch...

    Need Help with 8.2 Mercruiser

    Yes it could be. Basically will be down on power. What warning comes on? one thing that normally inhibits is the gearshift indicator seeing neutral. there is zero compression in end cylinders? would think exhaust is leaking water and hanging up valves @alldodge may have some thoughts too
