I have been searching the sight for anyone who has 370 cummins or similar hp engines to tell me what kind of fuel burn and cruise speed.I am hoping for 25-26knts while burning 24 GPH +-.I am in the final stages of repower and will probably have sea trial around the end of march.Cannot wait to take boat for a ride.

Mike, You're definately blazing the trail on this one. I don't believe anyone else here is currently running 370 Cummins. When Brian's re-power is complete we can compare 370 Yanmars to the 370 Cummins. Good luck.

Thanks Doug i will let you know how i make out.I have to run the boat from Delaware to Long Beach Island sometime in april.That will be its 1st test

Mike, did you install Flow Scans some other fuel management device? 1979 Bertram 33' FBC ALEXANDRA Port Richey, Florida HAVE YOU SIGNED UP FOR BERTRAM PRIDE '06 yet? DO IT NOW... SPACE IS LIMITED!

What is thetotal cost?

I did not install any kind of fuel management i will have to do an educated guess.The cost was 91,000 which included all new runing gear w/1 3/4"shafts.new generator+ac,replace a reserve fuel tank,new intakes water+air,new exausts,fuel lines,5 year cummins warranty on the engines which are 370 b reman.The work is being done by Carey Diesel in delaware and they are doing a great job.Also there is no sales tax in delaware

If there is a way for you to post a pic of how they look in the engine compartments, that would be great. Is there alot or alittle room? The cummins b series engines seem to be a very good and reliable motor. You are doing exactly as I would. Good choice Mike

Mike L - here's a picture of my installation. I have the 300 hp 6bts' rather than the 370', but they are the same size. I hope this works: [img]http://www.bertram33.com/images/uploads/stbd eng.jpg[/img]

Fraser, Interesting pic. What's the fan for? What do you cruise at with the 300's? Regards, Doug L. 1986 33 Bertram FBC Queen Elizabeth Marblehead, MA [img]http://www.bertram33.com/photogallery/p ... sabeth.jpg[/img]

MIKE L The picture posted looks to be the same size as the 370s.Filter +strainers are to your right+left when you go down between the engines very accessible.I am going to install a 6"rd hatch above the dip stick so i will not have to pick up the engine boxes to check oil.Thanks for the picture by time I would figure out how to post a photo it will be time for new engines

The big fans each move around 1800 cfm of fresh air into the engine room. One of the cautions I was given when I repowered was that the standard air intakes on the 33 SF are marginal for diesels. With the fans I don't have any air restriction problems and the temp stays comfortable in the engine room even at cruise. Cruise is right at 20 knots at 2600. I prefer to cruise 2450 and 18 knots fully loaded for a trip (plenty of beer, you know). I'm a little under propped.

Actually, I just changed the directions a bit to try to make it even more simple. I encourage Mike and Frank to both give it a try.

Frazer, looks like a real nice fit. Looks to have plenty of room to work around. Lot more than with the 3208's. If I ever have to, the cummins is the way I would go. Seems that support and part availability is the same as the 3208's. How smooth are they as far as running. I really like the way they sit in the engine compartment. With the 370 hp the boat should scream. I am definitly jealous. I like my 3208's and the 320hp is nice but man, the extra 50 hp is a big plus. Very nice. Can not wait to here what kind of #'s you get Mike..
