What kind of boat are you running your motor on?

1974 24' FleetCraft Express. It is a splash off of a 24 Formula. She is probably not quite as heavy as a Tsunami, but close with similar deadrise. Loaded with tanks, ice, and dive gear she can hit 47 knots and at 33 knots she gets close to 2.2 gpm nautical. http://www.classicseacraft.com/forum...0252#Post40805

I've had the boat out with the new motor several times now so I'm just past the 10 hour break in period. So Far I LOVE THIS NEW MOTOR. Everything that has been said about it is true. I only have a tach right now. The Navman is still on back order but hopfully I'll get it mounted soon so I can give some fuel burn numbers. Heres what can tell so far: 16x18.5 ss prop with 3 big guys jumps on plane in about 2 seconds. Cruises 28 knotts at 4300 rpm; 36 knotts at 5900rpm. The other day I hit 38 knotts at 6000rpm and bumped the rev limit indicator. Motor went into safe mode. That was with two adults and two children on board. I'm postitve I can hit 40 knotts if I stay at high speed longer then 30 seconds and play with the trim/tilt. Forgive me but Speed has never been my thing. This motor has more then enough power for the 23 hull. You cannot hear it running at idle, and at cruising speed you can talk to each other without yelling like the old 2 stroke. No smoke what so ever. The boat sits about the same in the water as it did with my old motor (weight difference: 522 for the yamaha 250 vs 580 suzki 4 stroke) It takes a little while to get used to the new sounds that the boat makes with this motor. So far I cant say enough good things about it. The only negative thing I've experienced so far is that the boat wants to porpoise slightly once in a while but that is easiy trimmed out. It's mounted on the 2nd hole. I'll post a full range of numbers when I get the navman installed. Here are afew pic's from the other day. My son was starting to get pissed because his sister had caught two fish and he had not caught any..... then bingo!

That boat is looking great. The engine sounds like a great match. Navmanfuel flow systems have been next to impossible to get. I hope you are not waiting on the F2100. I had one on my boat last year and couldn't get rid of it fast enough. This year I went with a Lowrance LMF400 setup and could not be happier. If you want more info on this stuff let me know.

I don't see Lowrance LMF400 on the website Jim.

yachtjim · #17 08-22-2006, 02:00 PM

If you do a search for LMF it will pop right up. You can get lots of info on it at lowrance.com too.

10-4 I put Lowrance LMF400 in the serch feature yesterday.

It's the 3100. Been waiting close to 4 weeks. dealer says it should be in this week.... well see I guess

Thanks for the nice comments. I still have a bunch of little projects to do on the 23 but for now it's been serving it's time on the water.

Well it's been 6 months since I put this thing on the back of the boat and I finally have some numbers for you fellas. 23 SeaCraft with a 250 suzuki 4 stroke, 16x18.5 prop, hard top, bottom paint and a 29 inch bracket. Conditions were FAC 1/2 tank fuel and two guys on board. GPS was used to get the speed and Navman 3100 for the fuel burn.

4000rpm 24 knts 28.8mph 9.5 gph 3.03 mpg
4500rpm 28.5knts 34.2mph 11.0 gph 3.10 mpg
5000rpm 33 knts 39.6mph 16 gph 2.45 mpg
5500rpm 36 knts 43.2mph 19.5 gph 2.21 mpg
6000rpm 39 knts 46.8mph 22.5 gph 2.08 mpg

Thanks goes to Tim (Bigshrimpin) for going along with me and for figuring the numbers. One of these days I'll get you on some fish
