    Prop change rpm gain?

    not sure you can fit a 16" prop on an A1G2 as it was tight with a 15". however rule of thumb is 200 RPM for every inch of pitch. still think you have a fuel issue.

    NO CRANK!!

    clean all the connections from the battery to the starter and block, then up to the helm. if you suspect the starter, pull it and go thru it.

    Regal valanti 170. Omc 4.3 v6

    get rid of the batwings before they kill your motor. simply google batwing manifolds no idea what went into the motor in 2018, however wont change hp much between cheap cast pistons or forged unless there was a blower on the motor. being in a boat, you are limited on cam choices

    Mercruiser 5.7 won’t make power

    yes, it should be steady if you are taking readings from the plenum. however you are most likely taking readings upstream closer to a cylinder so you will get pulses.

    Regal valanti 170. Omc 4.3 v6

    Going from 2 barrel to 4 barrel will gain you maybe 10-15 HP. Going to vortec heads will get you another 20hp or so So from your 37knots to maybe 40knots Did you replace the batwing manifolds yet

    Mercruiser 5.7 won’t make power

    Depends where you have the cam set and where the timing is. 15 to 18 inches of mercury is where I would expect at 0 up at idle with 8 BTDC base timing Bring the base timing up to 10-12 BTDC and you will bring the idle vacuum up. Did you get a fuel pressure reading while under load?

    Mercruiser 5.7 won’t make power

    I ran the same cam in the SBC on the Rogue. spinning VP DuoProp B6 props (about 23p) and pushing 4200# out of the hole almost instantaneously. I dont think its a prop issue. however toons are a different animal. the lower the drive in the water is does load the prop up a lot more, however...

    Prop talk?

    no idea. what drive ratio, what does your boat weight, and all the other questions that you must answer in the prop forum. for best results, you should have a Mod move this to the prop forum. (just report your thread, and the mods will move it)

    Idles great / misses when throttled up

    if this is accurate, you need to pull the motor and do a complete rebuild on it. the motor may run and it may idle, however it will not have any power did you over-tighten the rocker adjusting nuts? the ignition troubleshooting guide is in the stickies (adults only) at the top of the link

    Deck cleat question

    PVC has no strength, and PB will not stick to it. so even if the PVC was screwed to your boat, and the cleat is screwed into PVC, the first time you tug on the cleat, its going overboard with a section of your PVC trim and what ever it was you tied onto it. cleats on a boat normally go thru...

    E85 in Chrysler outboard?

    2-strokes do not do well with E85 or any high alcohol fuel without a really expensive fuel system and a lot of tuning if you want to save the environment with an old 2-stroke, either buy a really really good 2-stroke oil to reduce sludge build up in your exhaust (unburnt fuel and oil), or go...

    Having trouble finding points to elec conversion kit. 91 3.0 mercruiser.

    are you sure its play, or the mechanical weights moving. rotational movement is required for the mechanical advance to work. side to side movement is the bushings. if your distributor shaft has side to side play, you must go to NAPA and buy the two distributor bushings. bottom one is about...
