twin 140 zukes on a 23cc?

EVERGREEN · #1 01-07-2008, 11:27 PM

Don’t know your budget but I purchased a pair of used Yamaha 130’s from a dealer and rebuilt them. I have about $3,000 invested, $500 to purchase them and $2500 in parts to rebuild them. Performance numbers are not as good as a 4-stroke, but not bad.

4000 rpm 24knots/ 28mph 2.0 mph
4500 rpm 27knots/ 33mph 2.29mph
5000rpm 34knots/ 40mph 2.13mph
w.o.t. 42knots/43mph 1.4mph

Nice boat, what a deal on the motors. I have been looking for a used motor for my boat but have not found anything.

et23,
Keep an eye on EBAY this time of year. There are a lot of cheep 2-strokes available. Also, Suzuki 250 four-strokes that are being traded out for 300's.

Nice Suzuki 250 for $12,500.

Ed's is selling a brand new 30" Suzuki 250 for $12k right now.

$8,000 - $10000 buys a LOT of fuel.

3mpg vs. 2.3mpg

Atlantis, Veatch, Hydrographer Canyons aren't out of range now

here's some stats of a 29ft oceanmaster powered by twin 2.0L mercs . . . You can find a set of these for 2 - 3K and they'll give you similar fuel economy to the Yamaha 130's.

I think Im going to probabaly go with the 300 zuke. I think that I should be able to get close to 3 mpg at 30 knot cruise and maybe upwards of 2.25-2.5 at about 40-42 knots. with the standard 100 gal plus ~40 in an external tank in the console I should have comfortable range for veatch/ west Atlantis etc to go load up on YFT and BET.

older engines really arent an option for me. while they may save me some $ in the short run, I CANT have my boat in the shop in the summertime. Not an options with comm bass and charters going. I gotta be able to pay for this thing somehow.

Deuce, was that WOT at "lightest" trim angle? Your pic shows an angle of trim than will keep more hull in the water. I ask 'cause I used to run a 23' CC SeaCraft with twin transom-mount 140 Evinrudes that made a WOT speed of 48 mph. It was the tow-boat for a marina where I worked, and had a T-top as well. I would think you would get more from those Yamadogs.
