    bilge plug

    I just got a new to me sea ray. I put it in my slip for a couple of weeks and took on NO WATER. As it should be!! I hauled the boat out for maintenance and got a pop-up thunder shower and the way home, so had to pull the plug when I got home. Anyhow, this boat has a brass screw-in plug (I...

    15 hp Johnson - Throttle

    My tiller throttle is mechanically frozen. I can see the first linkage torquing, so it is not from there forward. I have ensured that the motor is not in gear, but that shouldn't stop the throttle from moving anyway, right? THis is probably something simple (it worked last time I used it just...

    1988 Johnson 15 - More Wonderous discoveries

    Alright. Rebuilt carb and replaced all fuel lines. Carb didn't look all that gunked up, and lines were in surprisingly good shape. Rebuilt and replaced lines anyway. I got to thinking more about my original problem. I had an overheat and assumed it was my impeller (never before replaced it). But...

    15 HP Johson - 1988 Coil Check?

    I have an old very reliable Johnson 15 that seems indestructable....been enjoying it for many years in very harsh duck hunting conditions. Last time out, I had an overheat....thought my impeller had failed. Even after engine cooled, could not start it up again.....lotsa almost starts, but...

    Gear Oil in Drive Shaft Bellows?

    I pulled my alpha 1 drive and the Drive Shaft Bellows had about a 1/2 qt of clean gear oil it. I suppose this came from the seal between the yoke and the bearings. My question is, I have an upper housing that has some scoring on the inside of where the drive gear bearings go. How important...

    Coupler Blew Up Today - Why?

    I was taking my boat out for the winter today, and had it in wide open throttle when bang, no more forward motion, engine still running great (but then overheating), and burnt rubber smoke in the bilge. Smoked my coupler no doubt, but what would be the normal cause for this? Did my outdrive...

    E-Coat or Silver Cadmium?

    I am strongly considering converting to Kodiak disc brakes, and my research has shown basically three finishes available ("e-coat, Silver Cadmium, and Stainless). I keep my boat in fresh water, and though salt water is only a several hour drive from here, I have no intent to dunk my trailer in...

    Gear Oil in my bilge; now what?

    I have gear oil in my bilge. 350Mag; Alpha 1 outdrive. I replaced the upper seals two years ago; if that's what went bad, what would cause another blown seal? Jake

    reassembly tip - alpha drive

    I have an alpha drive removed for annual maintenance and I split the drive to replace the impeller. Now should I first install the upper on the gimbal and then bolt up the lower or reassemble the whole unit before I bolt it back on. I am thinking the former is better since my helper is off to...

    upper gear housing swap

    I have a 350 Mag with Alpha 1 gen 1. I am replacing the upper gear housing with a used unit. When I put my gear assemblies in, does it need to be reshimmed? Since I don't have the right tools for this, I would have to take it to a mechanic; how many hours of labor should I expect to pay for...

    Holes in cavitation plate - should I repair?

    Because I destroyed my mercruiser alpha 1 lower unit in the desert we once called Clark's Hill Lake bordering Georgia/South Carolina, I bought a used lower on e-bay. Anyhow, the seller failed to mention that the cavitation plate on this lower had 7, yes, I said 7, poorly drilled holes on each...

    350 Mag Run-on Dieseling After Run

    My motorcycle guys and I were talking at work today about gas prices and octane issues, and I told them the reasons why higher than necessary octane was a waste of money. The rationale for using higher octane only if an internal combustion 4 stroke gasoline engine experiences pre-detonation...

    mercruiser starting problem

    1988 Mercruiser 350 Mag Alpha 1. No start. Fully charged battery, no click. Voltmeter shows slight draw when ignition switch placed in start position. Was able to start and run engine by jumping solenoid S and positive battery cable, which indicates solenoid checks out OK and kill switch is...

    Power Steering problems

    Year two of my restoration after boat sinking...... Power steering on my 21'6" Glastron with 350 Mag Alpha 1 was really stiff this year. My first inclination was that the contaminated hydraulic fluid in the system killed the pump, so I replaced it....no joy. I read some of Don's advice and...
