    Fresh or salt water? Change the oil and lube a 1500 -plus hours should be no big deal. You may run into the issue with MC-1 parts becoming obsolete, drive can be replaced with R/MR/Alpha gen 1 as a bolt in but trim/trnasom housing may be an issue Typical lake use in northern climates where...

    Mercruiser 140 Points to Delco EST results in low RPM at WOT

    I think the head design and ports also changed around 1990 or 1991 Quicksilver lists 3 somewhat diff part numbers for 3L heads 938 8M0115134 for 68-94 3L 938 8M0115135-1 for 3.0LX 90-97 938 8M0115135 for 98 and up

    Mercruiser 140 Points to Delco EST results in low RPM at WOT

    Give it a try the merc thunderbolt 4 & 5 for V6 and V8 use 8 and 10 degrees base timing and has a similar advance at idle. I would think 8 or 10 degrees would get you close enough to the factory advance it should run well at WOT. Would set it to 8 run it and see if you have detonation then...

    Ford 302

    Yeah i did the same when i repowered six years ago. bought a boat with a cracked 4.3 , went back in with a 5.0 beacuse that was the biggest engine offered with. in retrospect should have dropped in a 5.7. probably the 4 bbl upgrade isnt worth it unless you can find a used manifold and carb...

    Mercruiser 140 Points to Delco EST results in low RPM at WOT

    you are setting the base timing correctly, and total is correct, unless balancer has slipped so it is not indicating TDC correctly anymore. would also think fuel is ok based on your comments just thinking a sanity check as we may be running out of options . did the plunger for the power valve...

    Ford 302

    15-25 more hp. You need an intake, carb, fuel line and throttle bracket mods. I think the 302 ford came in both versions from Merc so you can look up what HP would be with both. I doubt you will notice the fuel consumption difference. I think you will find the smaller diameter primaries on a...

    Mercruiser 140 Points to Delco EST results in low RPM at WOT

    Are you putting it in base mode when you set the 1 d BTDC? And you have verified the 24 degrees all in timing with a light or you mean it should supply 24 degrees total advance? Have you checked the strength of the spark with a spark gap tester? Try with tach disconnected. Wondering if tach...

    $2500 boat

    Just keep an eye on the oil. My neighbor used his boat 3-4 times after he was too lazy to winterize before he saw water in the oil.

    The newer VP gas engines that I believe are still GM based go up to 5800 and 6000 rpm. https://www.volvopenta.com/en-us/marine/products/aquamatic-sterndrive-gas/aquamatic-sterndrive-gasoline-engine-range/v6-tcc/#specifications...

    Ford 302...21 foot fiberglass with cuddy

    Personally i prefer 4 blades. My primary use is loaded down water sports. Typically you will see better holeshot, lower planing speed at the expense of a little top speed with a 4 vs a 3 blade.

    Alpha 1 Gen 2 drive shaft seal?

    The seal is in side the upper housing so you will not see it from the outside. I believe the vertical drive shaft normally moves up and down about 1/4” so looks ok to me

    Ford 302...21 foot fiberglass with cuddy

    So with 10 degrees initial plus the 24 centrifugal you should see 34 degrees total advance by 3500 rpm or so. You can check this on the muffs just briefly rev it. especially with an older mechanical advance distributor that can get hung up or corroded, you just want to verify you Are getting...

    what size kicker should I get.

    On a similar sized boat (but fiberglass so would have been heavier than AL) had a 9.5. This was for a fairly large lake ( 40 mi long) for lake trout trolling

    3.0 volvo short or long block

    Yes the 1990 and up 3.0 will work for your application, you will also need the manifold and check the power steering cooler as that is probably busted too. Likely you will find the block cracked just below the head when you pop the manifold off.
