1975 23SF Repower
 

Thinking of repowering my 23 with a 300 etec or 300 Suzuki. Presently powered by a yammy 250 ox66 running a 17 pitch ss prop. Must say I'm leaning toward the etec. Advice and comments sought. Thanks

I have a 23 with a 300 Suzuki. My second one. I enjoy the quiet, performance and fuel mileage weighs in about 600 pounds and fly by wire controls.

I have a 1974 23cc still under the knife but getting close to being complete.. I just bought a 2012 f300 Yamaha 30" shaft with 64 hours on it.. Can't wait to see how this package will run..

If I had the money..........always seems to be a rather big issue. I'd put an eTec 250 HO G2 with a paint scheme to match my boat. Maybe it will help it's looks. I know it won't help mine!!

Please post results and performance either way. I have the same boat/OX66.

I don't know what kind of extra performance you expect from a 300HP given the cost difference with the 250HP :confused:

You will have all the torque, top end and GPH you want from the 250hp eTech. Stick with it and save the $$$$$....just my opinon.

I'd consider the G2 version of the E-TEC, probably the 250 HO version for a little lower cost but still plenty of power. Users are reporting that BRP is seriously sandbagging on the claimed fuel burn improvement! The advertized 15% reduction in fuel burn seems to be about right at WOT, but at cruise it seems to be more like 40%, which will put it well ahead of the 4-strokes! And while it's probably more expensive than the G1 models, it's really not that much heavier, when you consider that the weight numbers now include hydraulic power steering and a large oil tank.

Can't get used to the look of the G2 and I'm a bit fearful of any introduction of new tech - I like to give it a few years. Current promotions for G1 make it pretty cheap.

I can't get used to the look of Hillary either, however the G2 is much, much nicer!!!!!!! :)

Goes to show.....ugly is more than skin deep.

Committed to the 300 Etec. Installation next week. Can't wait.

Awesome! Keep us posted. I assume it's a G2?

No G1 - I'm old and fear new technology.

Hey I'm with ya, I'm old and fear Hillary!!!

That 300 G1 should be very, very nice on the 23. I would prefer you not tell me all the good performance numbers because I can't afford one!!! :) Good luck and I'm jealous!!!

Bombardier got it right the first time with the Etec....

I have an 05' 200 HO, first year out, now 2015 and running fine, better than fine.
Amazing the way these motors start instantly every time, quietly purr, and power up as only 2 strokes do.

Getting close - should be in the water this weekend

Prop testing today - 47 gps mph with a 17p but 6500 rpm; 49 gps mph with a 19p but 6100 rpm; shop is getting a 18p to try for 6300 rpm. Started chine walking with the 19p. All props 3 blade. Engine height looks good. Boat was light - only 35 gallons of gas and two regular size people. Best it ever did with the 250 OX66 was 42 gps mph with 17p at 5600 rpm. I'm hoping it will be pretty economical at cruise.

Very nice!! I see you have it up on the third hole which looks pretty good on the cav plate. I tried to help my brother last Saturday raise his 200 HO etecs up two holes because his cav plate is way too low , the two more holes is a high as it will go. As luck would have it the two lower bolts were galled on the port engine. Rest assured the installer knew they were galled, don't ask us if we were pissed!!! Anyway I'm jealous of your setup!! Keep us informed how it's going!

It those speeds are in nautical mph ..... That's rolling along pretty good! Best I've ever seen on my sled is 42 knots with my rattly ol 4 stroker.

Quit "Jones'in" for a new motah, Kenny. Those mid 2000 Zuke 250's are the John Deeres of 4-S. People I know have 4800 hrs. on 'em and they ran them since new at WFO. They spool up just like your's and when they chop the throttle - the sewing machine sound. You'er good till at least '19 or '20.

I know, I know.... Mama said I ain't getting a new one til this one blows up. The only thing that's killing me is that Robert can get me into a new 300 AP for under $14k! Like I need 50 more ponies and fly by wire controls......But I want it!

Not intending to derail the thread but I gotta ask moose - how hard do you have to run it to blow it up and get a new one? And how fun would that be?

You're killing me Ken!! You get the "itch" for a new Garmin....waa la Merry Christmas from Mel, now you want a new 300 hp Zuki wookie, can't you just wait until Christmas again??? Jeeez...... :)

It's an interesting game we play... I start looking at a new boat project and Mel overrides the process by upgrading my current sled. It's a smart move on her part but either way I win!

I cut her no slack and use all her ponies when conditions allow. Not sure what it will take to cook her but someday it will happen. In all reality it's all the power I could ever use but the new 300 AP is considerably more efficient and only 6 lbs heavier. I also have to consider how far offshore I take an 11 year old single engine out. Last weekend I made a 180 nautical round trip overnight. She could probably do 100 more trips just like it without a miss but it weighs on my mind.
