This is a bit of an open ended question, but hoping to find some loose guidance and direction. My wife and I own a 19ft ~4000 lbs boat. I tow it with my 2007 Lincoln Navigator without issue and I'm comfortable with it. We're looking at selling our boat and we have our eyes on something larger...

For anyone who finds this thread in the future: The issue was simply needing to remove the lines from the pump, ensure everything was clean and while reinstalling the lines, I made sure to take the pressure off of the nut by positioning the line in some sort of neutral relative position so it...

Thanks Bondo! When you say look for damage, are you thinking on the line itself or within the pumps receiving end? I'm not sure what I'd be looking for. Would that be repairable? This is one (of the few) areas of this boat I have never become familiar with.

Last year I replaced my trim / tilt pump because my last one would occasionally freeze up. I purchased a used trim pump, since I'm not sure new ones even exist, and it sounded much healthier while operating and worked great for the 1 - 2 times we took the boat out last season. This season, I...

Disclaimer: this is for a Yamaha Stern Drive, but that forum isn't perused much and this is likely a generic question that would benefit any brand of outdrive. My trim motor is not longer functioning. I tested the "up" and "down" relays per my Clymer's manual. Both relays "click". They also...

Yesterday while out on the river, my trim got stuck in the up position while shored up. Luckily, I remembered the "manual" override switch / valve on the hydraulic motor. I flipped that, stood on the outdrive and it slowly went down (while bubbling hydraulic fluid out the top of my pump...

I just noticed that my raw water pump starts making noise after 1-2 minutes of the engine running. It continually gets louder. I pinpointed the sound and touched the pump. It was so hot it burned me. I imagine the bearings are going out. I looked at a replacement and they are $750! The concept...

I've had nothing but issues with my Rochester Quadrajet and cannot find a local boat shop that will work on my boat because its too old (early 90's). After buying several reman's and having nothing but issues with each, I decided to purchase an Edelbrock 1409...

This is going to be a rather detailed sequence of events, so hang in there: I just replaced my carburetor with a new Rochester Quadrajet. I was previously having issues with my engine refusing to start after boating for 15+ minutes. This was random, so I threw money at it and bought a new carb...

First off, full disclaimer - this isn't about a MerCruiser, I have a Yamaha Stern Drive but my question would be universal and I know MerCruisers had Rochester Quadrajets on them like my Yamaha does... This forum has WAY more eyes on it. I have a Rochester QJet 4MV. I just bought it from a...

As the title says, I have a '91 Yamaha stern drive with a GM 305. I pulled all that Yamaha YEMS system out and put in a standard electronic distributor. Last year the boat ran fantastic - the best it has ever ran in the 10 years of owning it. This year, its behaving differently for some unknown...

I just replaced my exhaust bellows with a new one. While tightening down the hoseclamp, the exhaust bellows is squeezed off of the mounting point on the pivot housing. This is the only place it does this. It does NOT do it on the transom side of things. That clamps down fine and holds the...

I was doing some repairs to my sterndrive and it was in the (nearly) full down position. The hydraulic arms were extended maybe 2 inches. I later, absentmindedly, went to jack the tongue of the trailer up. I noticed at a certain point that the resistance on the hand crank became greater than...

I have a Yamaha sterndrive (a relic made for just a few years in the late 80's early 90's) and I've managed to keep it running for the past 20+ years quite well. All the time I've owned it, there has been a randomly timed "clanking" noise that I always assumed was the gimbal bearing. Happens...

Having an issue with the starter disengaging the flywheel after about 1-2 seconds of cranking. NOTE: I have disconnected the ignition coil, meaning the engine is NOT trying to turn over, this is strictly the starter attempting to rotate the engine. Backstory behind this is I had initially...

I actually have a Yamaha Stern Drive but I would tend to think my question would just as likely apply to most stern drives setups and this forum has many more participants... I'm removing my Chevy 305 engine from my boat to replace the flywheel (chipped teeth). Is it mandatory to re-align the...

This is going to be a bit long winded: I have a 1990 Yamaha Stern-drive with an 305 GM engine in it. Last year after frying the ignition computer that Yamaha put on these boats, I pulled all the computer controlled electronic Yamaha-specific stuff out of the boat and installed a Delco Voyager...

I have a 1991 Yamaha stern drive. Among the many issues I'm having with it, it grinds when entering either forward or reverse. The boat has done this so long as I have owned it (over 10 years) and hasn't been an issue necessarily, but it doesn't seem like something that is normal. What would...

I am *stuck* with a Yamaha stern drive and no parts available. I need a new impeller because it has been far too long since it has been replaced and I know I"m playing with fire if I take it out one more season. I have a 1990 5.0L Yamaha I/O. Also, does anyone know where I can pick up a carb...
