    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

    Thunderbolt IV

    no goes on a switch not sender completely different functions. 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

    Thunderbolt IV

    The low oil pressure switch will either be on top of block by distributor or down by the filter. The sender is for the gauge , the switch makes an audible alarm when oil pressure is low. Depending on the year the alarm system for merc sounds for low oil pressure, high engine temp, and low drive...

    92 would probably be a gen 2 , cut over year was 91 When merc started making them. had a 1991 sea ray that had by serial number one of the last gen one drives made, serial was just below the cutoff …unless a builder had a bunch laying around

    1989 Mastercraft prostar 190

    Depends on how you want to use it. The low deadrise hulls that give smooth wakes can be rough riding in some chop. If you are into skiing then go for it.

    1984 Mercruiser 470 Starting Issue

    because if you can fix it you can save some money. Have bought both project cars and boats over the years, and houses too... but you have to enjoy the project and have to have the skills to get it done. My current boat I bought with a known cracked engine block. repowered and saved a bunch of...
