Re: 260 Mercruiser thats been unran for years
Sounds similar to my situation. I put an offer on a 1988 mainship 35' sedan. The boat had been sitting in the water unsed. Total hours were quoted at 150 hrs for this 1988 boat with twin crusader 454's. I had a survey done and paid $650 with sea trial. <br />At survey, we had problems starting the engine. Both batteries were burnt out, well was dry. The broker ran to the marine shop and returned with new ones.Still it took a while to get the engines started and initally idling was rough and around 600 rpm. After we got going,I noticed the rpm on the port engine was erratic, hovering between 1500 and 2700. The starboard engine seemed to be running a bit smoother but soon died as we passed the harbor entrance. We turned around immediately and came home with a sputtering port engine. Just as we got halfway back in the harbor, we were able to restart the port engine. She flunked the sea trial!Other problems included <br />corrosion on intake manifold attributed to a leak ( I understaned this is common to 454 crusaders.) Both exhaust manifolds seemed to get excesively hot, est temp near 200 degrees.The engine itself remained at about 170 degrees on the temp gauges although we only ran to boat about 15 min before the engine died. I did not yet have the compression checked and at this time waiting for the surveyors report. The surveyor thinks the carburators need to be "replaced." the mainfold changed and both exhaust manifolds replaced. I wonder what other hidden surprises may occur later even if these things were corrected, given the poor maintenance record for this unused boat.I have not yet had the compression checked. The inital hull inspection appeared OK at the time.<br /> I'v been a single outboard engine boater and this is all new to me. I decided to move up to a bigger boat with twins inboards for the safety of offshore fishing in Hawaii. Appreciate your advice on this deal. Would all of these defeciencies be the likely sequalae in an unused boat or should I walk away, having alreay dropped for the survey? What would you guys do? My surveyor says "GO DIESEL." I could have the owner correct the deficiencies and have it re-inspected by a marine mechanic or proceed with the deal and negotiate a price cut for the mechanical problems(20k OFF 57k) and undertake the repair myself.
