Thread: 34'x11.5 Fibercraft Repower

  1. #1

    Default 34'x11.5 Fibercraft Repower

    Finally had a chance to run the boat today after installing twin FNM 300HPEP w Bravo two 2:1 out drives using SS 17.25x23p props. I expected to be over propped but with with 1/2 tank of fuel an three pax she hit 40mph @4200rpm which is 200 over the recommended and up against the limiter. Cruised at 31mph @ 3400 at only 60% load. With 5 more pax more fuel and gear she should be propped right. Will hopefully have some fish in the box by the end of the week.

    That looks like a nice ride. What does the boat weigh? I'd be interested in mpg and a comparison with prior engines. Thx.

    Finally getting some realtime data. Boat weighed in at 14,000 with 125gallons on board. With full fuel tank of 236gallons 8 pax on board she is cruising at 29kts@65% engine load.



    With an overnight fishing trip load of fish on board 150 gal of fuel and 8pax she cruised at 26-27kts @ 70% load and got about 1.25mpg for the trip.

    Beautiful boat. Is there a model name for the fiber craft. I'm interested in learning more about it.

    Thanks OT. The boat is just a 34' Fibercraft 1999 model. There are a number of them in Valdez built during the hay days when there was a very active charter fleet. The manufacture is no longer building a prodution line of boats but the builder did seem to indicate he would build one if someone really wanted one. I'm very happy w the performance and economy w the FNM 300s. Keeping the load under 70% she is cruising 27-29kts. Just completed and overnight trip and in 14hrs of running we burnt 200gal with nearly all of the time cruising w little idle time. Came back with a huge load of fish and still cruised @26-27 knots under 70% engine load.

    So, it looks like you got 2 mpg on your last trip, yes? 200 gallons / 14 hours - 14gph. 14gph @ 28 knots = 2.

    Very impressive for that size boat at that speed!!
