Long story short, my father in law recently purchased a 1991 Bayliner Capri w/ a Force 120. We've been having some issues with taking a while to start but were planning on working that out later on. We wanted to drop it in the water since we recently installed the prop and before putting time and money into it we wanted to see how it ran.
Out of water it seemed to run fine on muffs. We rebuilt the water pump. The impeller had lost a tooth and wasnt pumping water. After the replacement we had water flowing out of the holes and everything was good.
Fast forward to yesterday and we put it in the water. We started it up at the ramp and had water flowing and everything looking good. We ran at no wake speed for a little and all seemed well. He gave it a little throttle and speed picked up but it seemed bogged down so he reduced throttle and we kept running at a slow speed. Finally, the motor cut out and an enormous amount of smoke was pouring out of it. We got a tow back to the ramp and pulled it out of the water.
We took a look at the motor and noticed a couple issues.
1.) There was melted plastic coming out of the water release holes. Upon further inspection it turned out to be what lookes to be the boot spacer/spring holder just inside the holes. I'm guessing we overheated for some reason and it melted.
2.) There is a metal wire (coat hanger thickness) inside the motor where the boot attached. It has a hard plastic coating that had partially melted off.
When the engine runs it rattles pretty bad. I'm assuming its that metal wire piece making the noise. We are unfamiliar with this engine and I haven't had the time to dig into it very hard.
What is that metal wire piece? I can't find a good exploded view of this motor to find out. I've got a good feeling that engine has taken it's last voyage but maybe it's not as bad as i had thought. Made for a pretty crappy day. Especially being it's maiden voyage.:redface:
I guess I might as well ask another question. What's a good replacement for the Force 120?
