Yeah, I'm on my second prop in 3 years.
And she's a small I/O. 135hp 4 cyl Honda engine.
You got two props to last three years? I was lucky to get away with two props a year. My worst was when I had a bunch of friends down at the family lake house, and had a brand new stainless steel prop, and hit a submerged tree top less than an hour into the first outing. Grrrrrrr. It vibrates the whole boat and cuts 20 mph out of your top speed.
The Larson had a Volvo-Penta 5.7L V8, but it was useless with a perpetually bent prop. The SeaDoo boat had 360HP, and NEVER broke. Well, the batteries didn't make it though the winter in my garage without a trickle charger, but I could fix that myself. But, no exposed prop.
Ah, but Mother Nature can be cruel. I bought my perfect boat right at the start of a major drought. By mid summer, I could't put my boat in the water, because the water was 20-feet away from the boat ramps. Boat slips around here start at 400-bucks a month, and many of those were useless that summer. You couldn't get out of the Marina. So, I was making payments on a very pricey boat that I couldn't use. Bye, bye my friend.
Like they say, the two best days for a boat owner are the day you buy them, and the day you sell them.
