    rebuilding 350

    Hey guys, swapping out my old 305 for a juicer 350 in my 19' Mark Twain, a couple of questions about the 350. I know its good to buy a new cam and new lifters but.. if i marked each lifter to its lobe from the 305 to the new 350.. plus swapping the cam over would that be sufficient? When i did...

    800 series slipping in reverse

    It seems when i put it in reverse(while in water) it "slips" and i can hear something like loud "ticking" while in reverse and the boat definitely does not go reverse like it should(it still goes just VERY slowly). Forward works good, no noises. My guess is the clutch dog is rounded off on one...

    Belt removal

    My power steering belt snapped, seemed to be of old age (cracked and worn). How the heck do i get a new one on? Boat is a 1980 SBC 5.0. Seems the whole engine mount is around the belts, I'm just wondering if there is an easier way to do this.

Now...

    305 timing marks

    Hey guys I've got this Chevy 305 and my timing marks are rusted over the harmonic balancer so i cannot read them, I've read the Seloc manual and it was not very informational. Does anyone know what the notches are as i cannot set my timing without them. Thanks

    What engine/sterndrive is this? More boat info?

    Long story short, bought the boat a couple weeks ago, runs fine, i want to do some winter projects with it (clean carbs, gas tanks, upholstery, etc). I know the engine is a GM and that's just about all i know, the guy i bought it from claims it was rebuilt 300 hours ago but then again he also...

    72' Johnson 125hp charging output

    Anyone know the charging output of a 72 johnson 125 motor? I saw somewhere it was 2 amps at idle and 9 at WOT and was curious if it was actually true. Thanks.

    1972 Johnson 125hp no full throttle

    Hey guys, new to this forum and also new to boating, i've messed with jetskis but never a boat until now. I bought this 17' tri hull with a 1972 johnson 125hp "starflite" engine on. I cannot get full throttle, my rpm's are at 3900-4000 with my lever engaged fully in forward. I've taken apart the...
