HOLY CRAP Dr. Honda...I don't want that either!!!!! A rebuild every 100 hours?????? Are you kidding? What is that going to cost????? Also are those SC washers expensive? Can I replace them? Geeeze this doesn't sound good at all!
I know.
I love Seadoo... and I own a BUNCH of "New" toys... but all my watercraft are older, and have been projects. WHY?..... because I have a hard time making a payment on a toy that is parked 6~7 months out of the year... and I don't trust a used 4-tec.
OK... so, my Islandia project. Yes... I have a TON of labor into it... and I have about $1600 into my new engine. BUT... Even with my new Poppy cover, and the HydroTurf... I'm only into it for about $8k. AND... the going price for a 2002 Islandia is $12k to $14k. So, it's been a good deal. A 4-tec ski that I would be willing to buy, and pay cash for is going to be about a 2005~2006. (around the $4k range) But... those engines are 7 years old, and will start to have issues. IF, that engine gives up... it won't be worth it to fix it, since a new engine will be approaching the value of the ski. (see what I'm getting at?)
Now... a supercharger rebuild will run you about $1k per engine if you take it to a dealer. If you can do the work yourself... a rebuild kit, with tool steel washers will cost you about $150 per S/C. AND... the special tool kit is about $100. So... it's reasonable if you do it yourself.
Right now, the new 4-stroke PWC engines are where the dirtbike industry was about 10 years ago. They developed small, EXTREMELY powerful, high reving 4-strokes. Back then, not much was known, and they would get run until the had BAD failures. Now... we know that it's critical to watch the valve clearance. It won't move until the stems stretch, or the seats wear. And, at that point... the head needs worked on. People with the new generation of PWC 4-stroke engines need to do the same thing. A simple check every 20 ~ 30 Hrs can save a very expensive rebuild.
Before I bought my project... I was debating on buying a newer Islandia with twin 4-tec's. But it was killing me to think about the payment for all the months that it wasn't going to get used. Also... I was looking at a 2006~2007 model. They had the twin 4-tec's without the superchargers. Yes... it's less power... but it's less expensive, and less maintenance. (it's still 310 hp total)
