    Any issues with running this engine on a powerboat?

    J50EVLSIG 50HP but it's a "sail" engine with "special gearcase" 20" shaft which is what I'm looking for, fuel injected 2001 model. I'm looking to run it on a 14ft boat. It's currently on a lightweight 16 foot river boat.... have no idea how they ended up with a "sailboat" motor on it but the...

    Tohatsu 70A2 prop choice

    I'm going to move this engine from a 17ft CC to a 14ft CC so it's going to need re-propped. Closest educated guess I can come up with is a 17 pitch prop...which still may be a bit under... as this is a very light boat The boat is a 1987 14' Mckee Craft with a dry weight of 665lbs, 120lbs fuel...

    what's the difference 48SPL and 50HP?

    Why make a 48 when you already have a 50? Is there any difference (besides 2 claimed HP) in these engines? My understanding is the SPL stands for "special".... special what? Was there some rule somewhere about no engines 50HP and over that caused these to be made to "skirt" the rule??? I'm...

    1982 70 Mercury gear ratio?

    trying to determine what prop I need.... this engine came off of a pontoon boat (heavy) and is going on a 14ft McKee craft. Operating range is supposed to be 5300 - 5800 rpm. There are NO markings on the current prop so I have no way of knowing what pitch is on it now. Nor is the engine on my...

    Ok the factory manual shows a "pin" on the remote control linkage that's on the right side of the engine... IT says to remove this pin and push the rod towards the engine to disconnect the shift rod.... However..... that rod appears to connect to another rod thats pretty much in the center of...

    Tohatsu M70A2 fuel problem and coolant leak

    Hoping Tohatsu Guru or someone else will chime in here... bottom cyl is starving for fuel at all rpms.... squirt gas into that carb and dramatic rpm increase. Squirt gas in top carb very little change. Turn air screw in on top carb, engine quits.... do the same on the bottom carb, no change...

    Bolt hole pattern for engine mounting

    I considering making a trade with a guy (not for the engine on my boat but one I have on a stand) I currently have a 50hp Johnson (1987) and am considering a 50hp Mariner (1988) Other than swapping the controls should I have any mounting issues with the transom hole locations? Or is the bolt...

    1991 50HP Force, any comments on whether to buy?

    I've heard that some years are better than others... any particular issues with this model? I've been offered one at a reasonable price and of course will do the routine tests and checks before considering buying it. I'm just unfamiliar with these engines and would appreciate any feedback...

    possible to replace prop shaft seals without removing lower unit?

    Found the leak in my lower unit.... milky oil is seeping out of the prop shaft. Has anyone devised a way to change these without dissasembly of the lower unit? I was thinking a small sheet metal screw into each side of it and using a slide hammer to gently pull it out? Of course assembly...

    Odd fuel problem? 1987 40HP Evinrude

    Here's what it does. starts easy, idles great and accelerates to full throttle fairly quickly. once it gets to full throttle or sometimes just before it will "bog" then immediately pick up run fine for anywhere from a few seconds to a couple minutes and do it all over again. It also will...

    TNT draining battery

    The tilt and trim is somehow draining the battery rather quickly (with engine off of course). I've isolated it by disconnecting it from the fuse panel... the ampmeter then shows no drain... so it's definately in that circuit. However that's about as far as my troubleshooting knowledge...

    Nissan 50HP won't go over 4400rpm

    Recently bought this boat knowing that it hadn't been in the water for over 2yrs and the original owner did not drain the carbs. Initially fuel was pouring out of the bottom carb (3 carb motor). Took all three carbs apart and cleaned them out, no more flooding, motor idles fine and runs fine...

    Couple of MinnKota ?s

    How do I determine the model number? All I find is the serial number which tells me it's a 1999 model. It's a bow mount with foot control. The motor runs but it won't steer, I can hear the switches "clicking" when I push the pedal left and right but nothing at the motor, I see there's a...
