    Ford 302...21 foot fiberglass with cuddy

    Would think that should be ok, definitely safe for keeping detonation at bay Not sure what the stock merc was for that engine. What ever advance limiters were put in there must be limiting it to 14 degrees centrifugal advance.

    Mercruiser 3.0 No Spark issues

    I'm not sure if you are using what alldodge posted in post # 21 or the link I sent . In test #2 in what alldodge posted tests coil for short to ground same test is in #1 under ignition coil test in what I posted. If coil has short to ground I would expect no spark. Also as mentioned stick...

    Mercruiser 3.0 No Spark issues

    I would verify that since you have 3 tests not getting any ohms , also I assume coil isn't shorted to ground? You didn't mention that

    Mercruiser 3.0 No Spark issues

    As long as you got a good connection when sticking in terminals b,c,f meter probes may be too fat to get a good connection to the blade terminal inside of there.

    Extended Warranty

    I generally decline them, as I figure the manufacturer wouldn't offer the warranty if they didn't make money on the warranty sale and I am one of the weirdos who actually enjoys working on stuff so I am only looking at potential parts cost. Now if you are the one out of 100 who has a big issue...

    3.0 mercruiser ran for 5 min good. Then Just died?

    I would also check the anti siphon valve in fuel line by tank pick up is opening and flowing, also worth checking fuel pick up tube screen for debris if this hasn't been done. Some pick ups have a somewhat hidden screen in the pick up tube.

    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

    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...
