    Engine, Carb or Prop? need suggestions or ideas please.

    yeah, it does sound like a limiter, compared to yours. however, there is nothing like that on this mill. the rpm drop was me cutting throttle.

    UPDATE: took the boat out today to test. got a 4 blade 17p stainless (renegade 176575) in yesterday, so installed it to try first. temp was 89°f and about 70% humidity. time to plane was ~4.1s @ 18mph wot hit 4300 and 34 mph gps (13% slip) sounds like it was bogging, then backfired thru carb...

    yeah, internals should be quite similar for the 090m block. i've looked at a lot of boats in this size/weight range with the 4.3l. it seems like most of the 1.84 drives use 21 to 23 pitch and the 1.62 drives use 17 to 19. with mine in the middle at 1.76 i should be able to get 4400 or better...

    Scott, yes, the coupler is for a pre-1986 stringer drive. the couplers changed in 1986.

    i researched the sh!t outta the coupling when i got the new shortblock. it required the staggered-bolt starter, which requires the 14" flywheel, which i didn't have either of...so before i started engine assembly, i had to make sure a 14" flywheel would fit. then i had to make sure the coupling...

    hey kenny. the base timing of 6° is for 93 octane and 1° for 87. im running 87 non-ethanol (it's cheap and close). pressure is ~7# at 29gph according to my testing. when i get home im gonna post on cliff's site and get some opinions there on this carb. i know it wasnt built right when i got it...

    hey scott. i hoped you'd see this. :) the boat originally came with a mercruiser 470 and 23p prop. that was gone long before i got it. so my frankendrive is just that. the 800 stringer is from a 3.8 and when i originally got it (in 2011), all the parts were from a 3.8 and would barely run...

    i had thought that too, but everything i've read (on forums with well-respected experts) say that the 4.3 is already on the edge of detonation, and to never set total timing more than 18°. i have a chart somewhere comparing the 4.3 with the 5.0/5.7 and the v6 advance stops at 18°. OMC specs...

    hello fellow iBoaters. this is long post, as i want to convey as much info as possible on problems, what i've tried, and specifics on this engine. TL-DR - my sh~t aint working right and i dont know why. so, i've considered myself a fairly decent mechanic for the last 40 or so years, but this is...
