1991 Yam ProV 150
Replaced 2 lower units
a. Boat was rear ended at a stop light.
b. Boat was rear ended again in a parking lot which also took out the transom
6 plugs and lower unit oil every year
Has a carb, so it gets a little butt-faced in misty cold weather. Starts very easily, but in some weather conditions wants to idle like crap and you need to choke it a little and bump up the RPMs
Tilt/Trim switch burnt out on the bow. Fluke tester I used shown a direct short at the motor and I trouble shot the relays and crap for way too long. On the advice from a fellow IDO member, I replaced the two switches @ $8.00 each and was good to go.
Trim piece fell off the cowling back in about 1995. I put it in the garage with the intent of getting new connectors for it. It’s still MIA.
Friends kid had a temper tantrum in the boat and ripped all the wires out from under the dash. Went through hell getting that fixed.
From use it is showing its age. Doesn’t run as fast. I’ve lost about 5-6mph at WOT. The last compression test I did a couple years ago shown it lost 20 to 23# from factory specs. Only had a 3# variance in cylinders, so it has worn incredibly even.
That boat/motor has more hours on it than some IDO members have been alive. Every year I consider replacing it with newer/bigger….then ask myself why. I get butthurt thinking about the price tag on new and “improved” engine and see all my friends dumping huge amounts of money into their 225s and 250’s. For the same reasons I won’t buy a new truck. Too dam much money and too many more things to go wrong.
But then I’m an old fart with simple thinking. gas+spark+air = Explosion. Why complicate things?
Next, guys will be putting their engines on the dyno and adding performance chips/programing like a Pro-mod
