    Osco? Ever wonder what happened?

    If you are bored here is a court filing between Osco and one of their suppliers from years back . It specifically mentions some part of the agreement or actions taken by supplier interfering with potential sale to sierra...

    Mercruiser 4.3 Water in Oil

    Agreed you want to pressure test cooling system with intake on it. Could be a leaking intake gasket at water crossover. Maybe head bolts that go into water jacket ? wondering if break in lube used during assembly might be cloudying up the oil, or did u change it already? Either way would buy...

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

    Ok yes i used the term base instead of while in base mode set the initial to 1 deg….Still doesn’t change the fact that at one point merc used 8* initial with 36* total, and changed it to 1* initial with 23* total for some reason with engine rating at 135 hp

    From the 8* BTDC listed in post #10 its quite different.

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

    I recall seeing but cannot find at this moment a service bulletin on retarding the timing on some 3.0's that were blowing head gaskets, even included a sticker to cover the timing spec on the flame arrestor. I think they moved base timing back to 1 * ATDC.

    Ford 302...21 foot fiberglass with cuddy

    No wouldn't worry about the 14.5 to 15" diameter. typically within a prop family as pitch goes down you will see diameter increase. I think the TP 19"Pitch is 14" dia, 17"P is 14.5" dia , 15"P is 15" dia...

    Ford 302

    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...

    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

    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...

    Volvo Penta 3.0 GLP-D Choke/Starting Issue?

    You have to pump the throttle to set the choke , as mentioned pull flame arrestor off and see what choke is doing during start up

    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.
