i came across a 32" Blackfin that got banged up on hulls sides,bow and two small punctures in bottom.looking to sell a pair of cummins 270 hp storm block with 150 hours on match set along with ZF- 220 IRM gears in 1.53 ratio. (perfect for 31 Bertram) with 1 1/2" shafts,shaft logs.what it worth to you.you can also take the whole boat absolutely beautiful teak cockpit,coaming boards,teak and holly cabin floor.restyle cabin interior.------what ever?

bOB HOW MUCH ARE THEY ASKING FOR THE COMPLETE BOAT

ray i will take down serial numbers and cross check with cummins. they have been sitting BUT protected since 2011.engines are clean and look as new.i am not the least bit concern with making money or need aggravation and i will help a brother.

Ray

If you have any performance questions, that is the set up I have in my 31.

Bob-

I'm interested also. Any information would be great.

John

I am sure that the 270 s would push my bahia mar just great don't know much about ZF trans ratios. But i could get someone to haul to the jersey shore for a winter project. My chryslers are getting tired

ZF-IRM 220A is the best gears behind a cummins 6bta and 1.53 is the correct ratio for a 31' Bertram.the ZF gears weight 65 pounds and can be handled by one man in a tight engine compartment like the 31 in addition to real strong flat area to serve as rear motor mounts for engine and transmission mounting to boat stringers.trolling valves are easily added to ZF-gears.

Isn't tight for a trolling valve?

I'm interested but Ray and John get first bid. Please advise.

Unless you are looking to chase those Triple outboard CC's you will be more than happy with the 270's. Figure at 2000 RPMs she is at about 20 knots. 2400 you are pushing between 24 and 25 knots depending on how heavy the boat is.

These engines will run at 2400 all day long and they are rated to 2600. I top out with this set up at 2650 and I am just shy of 30 knots.

Off shore, how many days can you really run at 25 knots (Bob and Jimmy not included in this discussion, their boats are more than well tuned). Fresh water cooled after cooler reducing maintenance.

Life is never easy! insurance paid owner on hull damage then owner just let it sit there due to marital problems. yard bill is $23,000 so yard will go ahead with mechanics lien .i imagine they will hold a "Kangaroo court" on boat site and dispose of boat to high bidder.will keep you informed.
