    Upgrading Merc A1-G1 Oil Pressure Light with an actual oil pressure gauge.

    your oil pressure light uses an oil pressure switch. with no oil pressure, the switch is closed. when your oil pressure is above 7 psi, the switch opens. the switch provides ground to the light. the two wires coming out of the light do not matter with incandescent lights. one goes to the...

    Flap bennet issue

    the whole Bennett power unit isnt that much money. I would just replace the whole thing. the motor and pump combination were not intended to be serviced, hence the epoxy.

    Stripped threads on carburetor

    seriously, If I was going to swap a carb on a 4.3, it would be for a 600 CFM 4-barrel to get a bit extra power.

    Stripped threads on carburetor

    the issue is the split-top 500 CFM carb was used for only a very very very short time and was replaced with the much less expensive 2300 which shared so much with the 4150 there is one on ebay. https://www.ebay.com/itm/266999246488

    Stripped threads on carburetor

    I would get a new carb. if it was a holley 4150/4160/2300 series, a new bowl would be all you need. no need to be more than one finger on the wrench to tighten an inverted flare fitting. that little screen in there does nothing. it has a rating of 150 micron. which means that large chunks...

    What Brand of Brake pads are best quality? What do you guys use for quality?

    do you care about stopping more or not causing brake dust as much. if you want maximum stopping power, you are looking at semi-metallic brake pads. down sides is they wear the rotor more and squeak if you want minimal dusting, ceramic pads. less braking force than semi-metallic, minimal...

    Engine Swap

    you mean you banged on it with a hammer? wont sound hollow for a good decade after the wet rotten wood completely dissolves , then dries out or is eaten by insects in order to leave a void. assume any boat hull over 15 years old to have issues until proven otherwise.

    Regal 2100 take long time to get on plane

    fuel pressure taken at WOT will determine iff you have a fuel pump issue. since your compression is iffy based on post #1. you need to do a good job taking compression readings with a good gauge. then you need to take fuel pressure at WOT under load. 50 psi is the bottom of the spec. pic in...

    new engine overheats

    could your gauge be reading off? verify the temp with an IR thermometer. aim at the intake manifold cross-over just under the thermostat housing.

    how hot did it get on the hose? could have burned the flappers and rubber exhaust hoses.

    new engine overheats

    at 1000 RPM, the merc Alpha raw water pump should fill up a 5-gallon bucket in 16-20 seconds. it should also shoot about 6-8" up from the end of the hose if held vertically off there thermostat. I second Scott's theory that on plane is the raw water pump housing is leaking a bit and sucking in...
