    Merc Alpha1; Water coming into the Boat from the Transom!!

    Hi.. I've got a 1989 Rinker with a Mercruiser Alpha 1 drive. Saturday at the boat ramp, I noticed the sound of water entering the engine compartment *before* I lowered the drive and started the boat.. It was entering through a little hole (looks like a machined hole) in the transom plate just...

    I think I want a 4-Blade...Apollo?

    Hey guys (and gals), I own an '89 Rinker 20'6 Open Bow witha Mercruiser 5.0/4-bbl (230hp) Alpha 1 setup. I am currently running a Michigan SS 20P prop, which seems perfect as far as WOT (51 mph GPS @ 4750) and fairly good hole-shot. BUT, the boat seems to want to porpoise at cruising speed...

    L&S Torque Shift Prop setup question..

    Hello, I own a #126 L&S Torque shift prop (had it for 3 years), that I was using to get more power from a v6 I/0. Well, I sold that boat and bought a 230hp 5.0 setup. Runs great with a 19p SS prop (50mph) @ 4700, but I am thinking of putting on my shift prop for lower rpm cruising (starts at...

    OMC Cobra Lower Housing Froze! What now?

    Hello again guys...<br /><br />My 1986 Wellcraft froze the lower unit (water in the oil). The sides bulged on both sides, and has a ~3" crack on the passenger side which is leaking oil when the sun warms it up...<br /><br />Does anyone know if this is a hollow cavity, which can just be welded...

    4.3 2-bbl to 4-bbl conversion *UPDATE*

    Hello All,<br /><br />I wanted to update my progress, and ask a couple of questions to Bondo and RED regarding the conversion (see "4.3 Wake-up"....posting). I decided, based on brackets, $$, and estimated power to convert my (pre-vortec) 1986 OMC_Cobra 4.3 2-bbl (175 hp) to 4-bbl via Edelbrock...

    Hello everyone! I am preparing to swap my 2-bbl setup to edelbrock intake and 600 cfm carb on my 1986 4.3 Cobra (600 hrs). I decided to prepare by verifying compression on the 6 cylinders.

    4.3 2-bbl to 4-bbl conversion

    All,<br />I was wondering if a 4-bbl carb will hook up to the 2-bbl linkage with no real issues. RED mentioned that it required a bracket, but what about directly bolting to the carb? I have a stock 2-bbl rochester, but woould like to go with either a Quadrajet or edelbrock. <br />I've passed...
