Engine options....decisions, decisions, decisions....
Chuck,
I agree completely with Harry on this one. The N/A engine will generally require a lower pitch prop to get up to full RPMs so it won't be overloaded at 1800 rpms. Those engines are tough pieces of iron. I have two of them at 185 HP and would take that deal for the rebuild in a heartbeat. I do not think anyone is going to care if the engine is 25 years old as long as it is clean and you have the paper to prove it. I just wish I had freshwater cooled manifolds but since the current ones have lasted almost 17 years I guess I can't complain too much. I changing mine next week on the Port side just due to your story as preventative maintenance and yes they are about 1K. "Harry Krause" wrote in message ...

Have current 6354 turbo Perkins rebuilt by Pacific Detroit Diesel. $3600-3800, plus 10% markup to my engine specialist who can set up the deal and will handle transportation to and from the reman shop. Will need a new manifold for another $1k, and new innards for the aftercooler......(close to free since it looks like the aftercooler failed to bring down the engine and I bought the aftercooler several years ago from my engine guy). 2. Brand new Perkins Sabre tubo engine, about $14k and here's where it gets interesting....... 3. Brand new Perkins Sabre naturally aspirated engine, about $10.5k Especially with the super deal my engine guy is willing to arrange on the rebuild, I think I'd just automatically do the rebuild rather than the new turbo engine. But, the difference between the rebuild of my old turbo and the N/A Perkins Sabre makes it a tougher call. Anybody running a 6354 NA? I'd lose about 30HP, comparing the maximum ratings of the two engines, but I typically run about 1800-1900 RPM with the 165 turbo. I might lean toward the NA engine if I'm not going to lose anything more than about 1/2 a knot, (the Perkins specialist says I might even go a little faster with the NA at 1800 than with the turbo at 1800....hmmm). Another factor: Wife says there is another boat in our future. Not necessarily in the next couple of years, but certainly prior to retirement. She has a few items on her boat "wish list" that she thinks are missing from our present boat. General question: If you were considering a 25-year old boat, would you be much more likely to buy the boat and/or pay a few thousand extra if the engine were 4-5 years old vs. a 25-year old engine with 600-800 hours on a thoroughly documented rebuild? Such a quandry. Get the cheap rebuild and save the bucks for the next boat. -- __________________________________________________ __________ Email sent to will never reach me. |
