The co-owner of my boat, my girlfriend, and I had a discussion on what our recent repairs would have cost if we hired someone to do the work.
The following repairs were needed on a C310 2001'
Replace flywheel, damper plate (requires removal of engine), cutlass bearing, input shaft on a Hurth 50, motor mounts, raw input water hose.
Re-do packing, align strut (cut out 4" of glass, re-glass and shim), align engine, and install flexible coupling.
Parts and Labor?
P.S your probably asking yourself why would you need to replace the flywheel?
Because the manufacture put the wrong one on using the wrong damper plate that caused the failure to begin with.
In doing these repairs myself, I did not actually replace the flywheel, but manufactured an adapter ring to solve (2) problems, mounting the correct damper plate, and because of the thickness of the ring, it placed the collar on the new damper plate further into the input spline shaft where there was no damage, thus eliminating the need to replace the input shaft on the transmission. I also did not shim the strut, I drilled it out and epoxied the new cutlass bearing in correct alignment. So far everything is running very smothly, but only have maybe 15hr on it since. I spent ~$800. I doubt anyone I could hire for these repairs would ever think of solving these problems in the manner I did, saving time and money.
My point to all this rambling is, if you have limited financial resources, or just want to save money, but still would like the sailing experience to be on call (hey it's going to be blowing this week end let's sail) than learning how do your own maintenance and repairs is imperative. Learn about your boat, knowledge is money in the pocket.
