    1975 Boston Whaler with 25 hp Johnson

    Hi all, I recently inherited a 1975 BW with a 2 stroke 25hp Johnson, after a bit of tinkering, and some new parts (condensers, thermostat, coil, impeller, battery cables, and a kill switch) it is running like a champ. I do have a couple of questions though. First the restriction plate for...

    Cuts out at higher rpms

    Hi all, I'm hoping that someone can point me in the right direction. I have a mercruiser repower 357 alpha 4v. Which is just a standard carbed 350 with the thunderbolt v ignition. Before about three weeks ago it had been running great. On the way back to the ramp on Lake George. I was...

    Manifolds and Risers

    Hi all, I noticed that there was a little rust on my starboard side exhaust riser joint. Temps have been normal, 175-180, probably closer to 180. I can place my hands on both risers and hold them there. Although the Starboard side is hotter, neither is too hot to touch and I didn't notice...

    Runs rough at idle

    Hi there, I have a 2003 Bayliner 245 with a Mercruiser inboard and an alpha 1 gen 2 outdrive. I have about 90 degrees of play in the steering wheel. I first looked at the upper swivel pin as that seems to be the most common culprit, but stern drive and gimbal are nice and tight, which is good...

    Mercruiser 357 4v alpha

    Hi all, So being a old school car guy, I understand the impact that alcohol has on fuel systems, but I also know that if I run it consistently in my old jeep it is fine. The only real issue seems to be if I let it sit long enough to dry out. Shouldn't this basically be the same in a carbureted...

    Running the Alpha 1 gen 2 stern drive without water

    Hey guys I'm new to boating and I was having an issue with my mercruiser where it would die when hot. It has an inlet hole line rather than muffs. So I ran it for probably 20 or 30 min that way while carefully watching the temp. Idle up to 1500 rpm. Turns out I had a bad coil, but now I'm...
