alpha one

I just bought a 1997 Sea Ray 175 3.0 merc Alpha One. I was just feeling how soft the water hoses were by squeezing them and the elbow at the pump crunched. I took it off and found this: Should I pull the manifold and other cooling parts clean or replace? Is this the manifold flaking...

prop markings are not very visible but this boat has what I believe is a 15p prop three blade aluminum. Seems very underpitched for the engine and at nearly 4k rpm tops at barely over 26mph. I'm considering a 4 or 5 blade SS 21+ pitch prop. I pull skiiers sometimes but interested in power and...

This is not a selonoid issue, I am by-passing that by jumping the pump. While jumping, I used the wrong wire. There is green and blue. I jumped the green wire my mistake, which drove the drive to its end of travel going up. Dumb mistake. The pump still runs, but the drive won't go down, when...

I have been searching this forum and other internet sites and I can't find a definitive answer on how to flush the elbows (aka-risers) and manifolds on my 2005 Sea Ray 185 Sport (4.3l Alpha 1) while in the water and NOT using muffs. Biggest issue I believe is the Alpha 1 has the impeller in the...

I just purchased a new to me 1998 230 Overnighter with a 5.7 L 250 HP and Alpha One drive. The boat only has 250 hours on it and runs great. I had it checked out by a repuatable marine mechanic before I purchased it and had him install a new 3 blade aluminum prop 15x17 i think. I took the...

I have pulled my outdrive for maintenance and found a plate, broken and resting in the exhaust port. I have located the part at the following url but do not know where this part mounts. Does anyone have a diagram or pics showing where this mounts? part...

I just got a 94 searay bowrider 5.7 alpha one. I just replaces bellows, thermostat, and water pump. Just took it out and w.o.t. from a stop the motor bogs down for about 3 seconds around 2k rpm. Any thoughts? This is not a constant problem. Fuel filter? Wires? Plugs? Also, unrelated, steering...
