We extend to you a cordial "WELCOME ABOARD !" Come on in, make yourself at home, we are a friendly group of enthusiasts, and we also appreciate the classic Chris Craft Roamer, Corsair, and Lancer boats too , as they are all on the same family tree and share much in common !
Paul and All,
My knowledge of diesels is limited, I do know that they are inherently leaky and a bit more messy in the bilge than my 427's and do require a little different style of maintanance. I like the concept of all that torquue at lower rpms for the large boats and get the whole "diesel thing" but I personaly have never and will never turbo charge or supercharge any gas motor that I own due to the lesser life these options offer. I have to believe its the same issue with diesels, having said that if I were to own a turbocharged diesel boat I can honestly say it would be a pampered life for all that power because I'm not going to be chasing any tuna or white whales for that matter. The 485 HP's are there IF you need them but my style of boating is cruising for the most part so in my quest for the next "adventure" has all options on the table for the right combonation of style, reliability, maintanance requirements and pricing, turbo, gas, rocket fuel etc.
I've read some ideas of how to detune these motors by under proping them, changing out injectors etc to prolong the life but it seems the more I read the most confusing it gets, kinda like a good resturaunt with a huge menu, way to many choices or like John Kloka once told me, if the menu isn't on the wall behing the counter then just walk away....ha!
One question I have regarding the oil in the diesels is that when they test the oil what exactly are they looking for and what is the prognosis of "good" or "bad" oil dictated by? PPM's of metal, Ph, viscosity?? or all the above?
