Re: single or twins - 23 CC
 

All this input has been very helpful. Thanks everyone. I think I'm gonna go with a single 300 Yamaha.

Have a Yam 200 ox66 on mine and its fine, you dont
need a 300

Re: single or twins - 23 CC
 

Good choice John... I'm guessing one of those new 4-stroke V6 300's. Didn't know you had a project like that. Anyway, hope all is well and don't forget to post some pictures.

Re: single or twins - 23 CC
 

I wanted to ask the same question and stumbled across this thread. But I have a different desire. I want to use a 23CC with a hermco bracket and run from Boston Harbor towards Newport R.I. occasionally. And mostly fish. With the conditions around here and the time of year for fishing (into October) I don't need speed. And a 4 stroke (or two) is a must as I get seasick fast around two strokes. As is getting home. 25knots is fine for me for speed. But I was wondering about the weight of dual 4 strokes on a bracket. Like dual Honda BF90s or BF115s?

Haven't bought the boat yet, looking at a 23CC, maybe a 20CC with a bracket and trailering it more.

Ouick story on this......years ago a guy was docked next to me at the same place as I was staying and had just had his twin 2-strokes replaced with twin Honda 130hp on his 25' Pro Line which had a bracket. Was so proud on his decision to upgrade to 4-strokes, save on gas money, etc. One problem, it would not get on plane properly, way too much weight versus the two strokes. Had to trim the engines all the way down and put the passengers to the front to get on plane. Keep the Honda 4-stroke weight issue in mind.

Re: single or twins - 23 CC
 

yeah, that was why I was maybe thinking dual 90s at 365 lb each. For some reason I think earlier BF90s were lighter at a 1000cc size but I have to go google that.

Re: single or twins - 23 CC
 

i dont think you will have enought power with anything less then 120hp but i may be wrong i have twin 130's and it seems perfectly matched jumps out of the hole and cruses easily at around 30 at 4000rpms as far as top end i haven't ever opened them up but they respond to throttle input very well to adjust to what's happening up here in out very unpredicable weather and sea conditions but keep in mind it's a complete dog with just one running but it is still going foward or out of danger!!! as far as a 4 stroke my 2 smokers are a lot of weight on the back without a flotation bracket also keep in mind the new 2 strokes are very clean burning so dont rule them out just yet i would love to put on a 250 e-tec and loose some weight and double my mpg's
just my 2 cents don't hesitate to get a hold of me with any other questions

Twin 200 HPDI's on Trayder's conch 27 is stupid fast and that is a much much bigger boat that cruises at 40mph+. Twin 200's is totally unnecessary on a 23 seacraft.

Re: single or twins - 23 CC
 

Yeah, I kinda agree!! If I had my way and the money....my wife says I can't have my way and I know I don't have the money.....soooooo I would have either a single 250 or if I wanted to go crazy twin 150 ETECs on a Hermco bracket. My 'ol 225hp single does a very good joob and I really think anything over 300hp is serious overkill. My two cents.

Yes, but there are few things in life like the sound of two big two strokes and the smell of twice the oil. :D
