I've never posted here, but have learned a ton from searching through the archives. Thanks to all those that have posted.
I have a 1988 175 Black Max.
It has run pretty good since I've had it the last 4 months, but I started having a few problems in the last week.
First, my alarm wouldn't always do it's self test when I turn the key. Then it gave off a weird ghastly sound when getting on to plane a few times. All oil reservoirs are full and temp is not high.
Now to the bigger problem.
When I engage the throttle (or idle lever) it sounds like it's trying to go but the RPMS stay relatively the same. Eventually, it seems to catch and the RPMS increase and it runs great all the way to WOT. When it catches a big cloud of smoke is spit out.
I have tried to pump the bulb, but it does nothing when hesitating. If I try to just gas it the motor sputters out. It is especially bad when trying to trailer the boat.
At first, because of the alarm (i think) a few people from another forum thought it could be the oil pump (nylon gear) I took off the oil pump and inspected inside the block for any damage and it looked normal. If it was the oil pump I don't think I would have a running motor right now as I have run it almost WOT. Wouldn't I even be able to WOT if there were fuel/oil delivery problem?
I talked to a guy who I buy parts from and he thinks its the stator. After some research I found that it could be the low-speed coil, not sending the proper amount of power (too much or too little) He also thinks this because I blew my rectifier awhile ago, but kept using my boat for a few trips. He is sending me a flywheel puller so I pull it off and visually check the stator. Could replacing the stator fix my hesitation problems and maybe the alarm too?
Anything else I should try? I plan on getting a spark plug checker and checking the plugs ASAP.
Sorry for the long post. Thanks for your help.
