    Force 75 threw a magnet at us

    Ok I did find a flywheel I could afford, actually a flywheel, stator, and trigger for $150. Be a few days before I get it on the motor and I'll update then. Thx jerryjerry, I did think that a bad tach could bother the ignition so we tested previously with it disconnected but there was no...

    Force 75 threw a magnet at us

    The tach wiring checked out ok but haven't tested the in dash tach hooked to the AC yet. I don't see a problem with the reed valves. Guess I'll start looking for a flywheel.

    Force 75 threw a magnet at us

    There is a spring and the rubber seal looks fine and for sure the motor is not overheating. The wiring in the boat had previously been replaced. Before and after replacing the regulator a second tach was installed directly to the regulator and did not respond. When the second tach was wired to...

    “And the plot thickens”. Found something interesting during the seafoam run. The boat we put this motor on had a temp gauge so I put a sender on the motor, there were other concerns at the time so I kinda forgot about testing/calibrating the temp gauge. Unfortunately this lead to ignoring it...

    I will inspect the reed valves, running the seafoam thro it now

    Force 75 threw a magnet at us

    I've already got the seafoam so I'm going to go head with that, next time I will get the Techron. I disconnected the primer and plug the line to the carb but it did not make a difference. I like the snake cam idea, I be looking for one right away.

    Force 75 threw a magnet at us

    If the seafoam doesn't make a difference I think what I'll do is try to find a seller on ebay that would rent me their flywheel, if it works I buy it, if not I pay a fee and send it back.

    Force 75 threw a magnet at us

    Thx Redbarron, I did isolate the cylinders earlier; " Ran with each plug disconnected, with #1 only a slight diff, with #2 it was a bit more noticeable that meaning rougher idle, #3 it would barely idle. Swapped CDI coils 1 and 3 but symptoms did not change #3 still effect the idle to the point...

    Force 75 threw a magnet at us

    I'm an a**, you can forget the symptom where I mentioned it would cough and lose rpm. I was setting up to do the seafoam cleaning and thought I would inspect the plugs first, bottom plug was not tight. I had the plugs in and out a bunch of times and don't recall the last. So here's where I'm...

    Force 75 threw a magnet at us

    Got the new reg/rect installed. No battery draw with everything off, (old one was at 25ma). Not sure how to prove it’s doing the battery any good, before starting battery was at 12.5v. Rev’d the motor a bit and it didn’t change, at that voltage maybe it shouldn’t (?). It's Sierra and has 2 red...

    Force 75 threw a magnet at us

    Sorry to hear that you couldn't come up with that flywheel but I sure appreciate you looking. Not sure why the Force ones have turned to "gold." I should get the replacement regulator tomorrow, I'll get it in right away, test, and update.

    Force 75 threw a magnet at us

    That appears to the flywheel, but I don't believe you can tell the difference with the trigger magnets. Guess I should say I don't know how to tell if it's one row or two. I do know by part number research that the 1996-1999 all used the same flywheel, any one of 6 different units.

    Force 75 threw a magnet at us

    Yeah good point about the cost, might look for a complete outboard if the regulator doesn't help. Thx

    Force 75 threw a magnet at us

    Thx for your reply. Not so sure I can say what the revs were. I only had it opened up once and because I wasn't sure if the tach was right I didn't stay there but a second. When the tach was stable it was about 5200. I did order a new regulator so we'll have another look in a few days. I did...

    Force 75 threw a magnet at us

    Let’s see if I can sensibly describe my outboard problem so someone can suggest where I go next: Bought this 1997 Force 3 cylinder 75hp on a bass boat. First go over; fuel system all new, filter replace, plugs ok, compression low at 115 but all the same, started and ran on the water hose no...

    "Cold Fouling"'

    About at the end of my rope or should I say "line" on this forum, with my older Merc outboard. Been thro a lot with it but I'm about to give up unless someone can help. Here's what I'm up against now; '75 inline Merc 1500, 150hp, carbs removed, cleaned, adjusted, fuel lines and components...
