Hopefully you guys don't beat me up too much for asking a question on a non - Sea Ray boat, but I just can't think of a place that has more knowledgeable folks than CSR. Didn't think we would find ourselves in a situation where we are buying something other than Sundancer, but we came a cross a trawler at a boat show that we absolutely fell in love with.
We had the mechanical inspection yesterday. The boat has a single John Deere 12.5L diesel model 6125SFM75M4. This is a commercial duty motor with 610 hp rating. The boat is a 2008 45 ft semi-displacement hull. It's a one owner boat that spent the last 10 yrs in a boat house and clearly has been loved and cared for. She has about 1250 hours on the clock.
When she was built originally, the owner had John Deere do all sorts of tests as part of commissioning. I was able to get my hands on those test results and compare them against the results from yesterday.
Per John Deere specs, the max RPM is 2100. When new, JD did 5 test runs and achieved an average of 2118 RPM (the range was 2125-2114).
Yesterday, at WOT, we were able to get to 2060. We had very calm water yesterday, so that was pretty nice. We also had similar load. I do not know about the condition of the bottom paint and props. We'll find out on Mon when we have the survey.
I know that the boat was well maintained, but the owner passed away about 3 years ago and the boat has not seen a whole lot of use. If I had to guess it was started a few times, but wasn't ran consistently most likely.
My question is, should I worry that we were shy 60 RPM from when the boat was new and is the fact that it sat around for at least 2 years something I should be concerned about?
