    What is this wiring connector?

    Even if the connectors are not the same you can make your own from -to cable if you go on line you can find these marine and automotive connectors and make up what you need

    VP 5.7 WOT RPM question. Is 4100 RPM low?

    Your should be min 4600-5000, i think so e of the Merc mpis go to 5200 on the same block. bottom line prop it such that you get 4900-5100 light load and the performance will be good. i would verify your tach is accurate and in good working order. what is yiur speed at 4100 rpm

    2002 Mercruiser 4.3L MPI Fuel Pump Style

    just a note to OP - SAE J1171 will be on all electrical components ( maybe fuel components too) that are marine rated. Vs automotive the alternators fuel pumps distributors etc will have design features to prevent spark and fuel vapor explosions and fire . it not the part number for the component

    Merc 470 modifying water pump seal problem

    I have no first hand experience with the 470, but generally the speedy sleeve seems to work for folks . If you are having these repeated failures there is another issue thinking maybe misaligned timing cover or bent cam snout, wrong speedy sleeve , issue with water pump to cam alignment. Yes...

    Merc 470 modifying water pump seal problem

    you are taking about sea water pumps not the block circulation pump tgat the op speaks of. Your 454 will have a circulation pump mounted to the front of the block over the timing cover. This circulates water through block and heads, and is feed by the crank mounted seawater or raw water pump.

    Volvo Penta 5.7 GSi PLKD timing mark out of scale

    Another likely difference is the original engine (assume 96 or newer) had Vortec heads, 85 would not have vortec heads, big airflow and hp difference between them . If your block has the bosses for roller lifter guides swap in the proper marine cam and lifters, vortec heads if needed

    Eagle , Scat rod question

    Vortec head version is 340 hp, 425 lb ft torque. Agree with the others dont hammer it too hard and a gen 2 will hold up ok. This has the stock hp and torque numbers https://www.michiganmotorz.com/6-2l-377ci-stroker-base-marine-engine-2000-2019-replacement

    Oil pressure switch is usually on a 1/8” pipe T down by oil filter . One side of T has the oil pressure switch (two wires going to it) and the snder for pressure gauge ( single wire bigger dia sensor). take the wire harness plug off the switch put a jumper wire across the two wire connections...

    1996 Seadoo SP- Not running, good project?

    wouldn’t have high expectations fir this one and wouldn’t pay $300. id look in the cylinders via plug holes for detonation . If carb is “broken” likely it has plugged passages and was running lean. Its one thing if you clean out fuel system install carb and use it for a season or two. Its...

    Old ford 302 no spark

    it was under load when you were trying to get past 2 k rpm. Point he was trying to make is if you set it by ear which is in accurate it is likely you may have timing too far advanced, which leads to detonation, which will burn a hole in a piston. Loads on marine engines produce a much higher...

    My two very good friends who keep boats there have more concern corrosion potential from stray electrical current In marina in this area. i keep my boat on one of the finger lakes in NY, fresh as it gets… since swapping on a big SS Revolution 4 prop i get corrosion, its not just the salinity...

    Old ford 302 no spark

    Once timing is set also check your advance is coming correctly. Im assuming you have mechanical weights for advance these can get hung up. Lack of full ignition advance can limit rpm as well.
