Hi everyone, I'm doing a survey next week on a 05 Sea Ray 340 8.1 V-drives... It has org manifolds and rises, with low hrs... I know hrs don't matter on maintenance items as for those... My plan is if I do buy it,,, Change manifolds & rises, Oil coolers, Trans coolers, and maybe shaft seals since while I have the manifolds off I can get under the engines... Whats everyone's opinion on org manifolds & rises from 2005???
Check to see if you have aluminum or cast iron manifolds. The aluminum one will have to be swapped out if they haven't already. Manifold are considered an expendable maintenance items so maybe remove and inspect, then decide? Risers.... they are pretty sturdy, not much going on there. Again, maybe at most remove and inspect since you are doing that to the manifolds. If you end up reinstalling the manifolds, give the manifolds a really good rinse while you have them out. Plan on replacing all the sensors because they don't remove easily after the plastic has been heated over and over. I hope you're a small guy.
