I bought a jetski project for next to nothing during Christmas time. It is a 93 Arctic Cat Tigershark which has the stock 2 cylinder 640cc Suzuki engine. I guess they didn't make their own engines.
Long story short. The parts aren't available from more than just a couple places. The main problem is the crank shaft bearings. It needs 4 bearings, one is $106 and the other 3 are $70 a piece. They are all the same size but the $106 one has the snap ring groove in it.
But I searched the bearing size and found the correct size and style bearing for $8 a piece from a bearing place. The only unknown is if the groove is in the right location.

Let me know what you think, thanks.
