never had the chance to go on a 390 with Diesels,
but from what i have been told there is really no difference between the HO's and Diesels in low speed maneuvering around the docks,
only difference is over long distance which from what i was told/researched is only about 30 miles difference,
prior to sea trial and survey, the owner took me out for "test drive",
the only thing i need to get use to is looking out the windshield vs looking over on other boats which is what im more comfortable with at night,
boat pulls right up on plane with no issue with the HO's and held on plane 22/2300 rpms @ about 15mph with no tabs while backing off the throttles slowly.
not very efficient, but was impressed to say the least, a lot of boats of that size fall off 2500 or higher with gas
very excited time, all paperwork is in for financing and ill know all the details by the end of the week..
Just curious whats your fuel burn like with the diesels?
We cruise around 2400 RPM burning 26-27 GPH. We have friends in the marina with the 2005 390 with the same engines. It really is a great boat and handling around the dock isn’t an issue. We noticed a significant difference with the QSB 425’s with low speed handling. The responsiveness is greatly increased. I have been very pleased with the Cummings engines the down side is you pay a premium for them up front I am just hoping to get that back in resale.
