I brought my boat/ motor in for some general maintenance today . My motor was running strong with no issues but I thought it wouldn't hurt. I had bought some parts online from Browns Point Marine for my Suzuki 1999 DF 70. I replaced the timing belt, replaced the High Pressure and inline fuel filters, replaced the impeller/pump kit, they did some adjustment on the throttle cable and gear shifter. Mechanic said he replaced the timing belt but the old one was still okay, everything was good and that they don't motors like that anymore. I'm glad I finally got around to doing some motor maintenance . Labor was $ 129.99 / hour . So with parts and labor it was about $ 1000.00 , that's about $100/year for for the 10 years since I own my boat not including winterizing and gas. That's really is cheap for all the enjoyment I get for six months of the year fishing.
