I purchased this boat in 2010 and have battled a bad vibration ever since. The prop shaft was bent so I replaced it and the vibration persisted but wasn't quite as bad. I found that the incorrect rudder had been installed at some point so I corrected that. This summer I decided to check the alignment of the engine and shaft coupling and wham...there it was. Engine was out of alignment. Realigned it and it ran butter smooth. After several more hours of operation the vibration was returning. hmmm...whats going on? Aligned it again and it's butter smooth...well after a 3rd realignment it was obvious the stringers must be allowing the engine to sink.
When I pulled the engine 5 of the 8 lag bolts just pulled out.....the other 3 were bent and were real buggers to get out. After pulling the carpet up the floor is in very good shape, no signs of wetness at all. The stringers themselves do not seem to be soft or spongy but the lag bolts tell the story. Although they are not completely mushy rotten they have deteriorated enough that it's time to replace them. The great thing about this boat is that the main stringers are totally exposed such that none of the floor needs to be cut in order to replace them.
I have read many of the stringer stories in here and although I know I am capable of doing the work I lack the space and tools to do it. So....I took it to a shop named Fiberglass Products and Boat Repair in St. Joe Indiana. Some of you may know the owner. His name is Tom Miller and he was a partner in Hydrodyne and it's predecessor Crosby boats when they were made here in the little town of Harlan IN. The factory is still here, but they make commercial furniture and cabinets there today. Hydrodyners.com Tom is 75 years old and has built boats his entire life. I think Foobiehazzie is in great hands.
I dropped the boat off last Saturday, October 27th and he said he would call me once he got a chance to get the numbers together. He commented on how solid the floor was and I believe he was shocked at the condition of the boat for it's age. When I first called him I could tell he was a little apprehensive about working on a 32 year old boat.....but he was excited to see the condition once he got inside it.
I intend to clean up the engine, replace all the hoses and belts. I can still buy an original interior for this boat through A&A Marine century upholstery So I guess I'll be posting pictures as I progress. You can view the public facebook page for Foobiehazzie where I've posted an album of the deconstruction. It has to be ready to go for next season...I plan on splashing it on or before memorial day!

. For 1,100 hrs it's still a strong motor. Compression tested it before it came out and all 8 are in the 140-145psi range. Not bad for a 32 year old motor.
