Twin 140 4Stroke Suzuki's

Thinking of putting twin 140 4Stroke Suzuki's on the back of my 23 Seacraft. Just wondering what kind of cruising speed I should expect and at what RPM's, fuel consumption, and WOT. Oh yeah, how much money would two engines cost me. Thanks for any input.

I think the Suzukis go for like $8000 a piece. While we are on this subject, I heard that the Suzukis and the Yamaha don't stand up to the saltwater all that good. Any comments on this from anyone?

I don't think I would hang twin 4 strokes on the back of any 23' boat unless it had a large floatation bracket along the lines of a hermco or something of that nature. Your sculpers will probably be permanently underwater, and the boat at rest is going to sit real low in the back.
One Suzi 140 is 410 pounds. My 250 Merc is 472 pounds. 820 pounds is alot of weight to hang off from the back of a 23' boat. I would want at least 400 pounds of positive bouency underneath them. A buddy of mine has them on a 23' boat and gets around 3 mpg cruising at about 27 mph. As far as reliability, the suzi's and yami's that I know about seem to hold up pretty well. All manufactures make a bad motor or a whole bad lineup/year from time to time (Merc, 'Rude, and yes even Yammis). Unforutnately, if you buy a new one, you won't know until it is too late (lol).

Well, as far as economy my DF 115 runs on air. I don't know how many GPH or MPG's it gets but it's alot.

As far as curosion goes I don't think it's worse that anything else. This is my third season and it seems to be holding up pretty well.

The corrosion thing is on older Suzuki engines, the older four strokes I looked at were no worse off than anything else in saltwater. My new 140 (85 hrs. since July 3rd.) has the luxury of living on a trailer and gets soap and water after every use no wories here [img]images/icons/grin.gif[/img] . Like Finster said they use no gas I put 12-15 gallons in my 20' every ten engine hours I'll post the exact fuel numbers in the near future. I just gassed up tonight and gas went up ten cents a gallon this week super was $2.03 [img]images/icons/shocked.gif[/img] at the Mobil. I was really loving this engine when I saw the gas prices this week, they love to nail you for Labor day week end. Great engines [img]images/icons/grin.gif[/img]
