I have saving saving saving now my motor went on week end, ha ha still dont know 115 of 140 suzi.

For a viking 17 would a 115 pull it out of bog quick enough? Want to use it for offshore............ so the bar is the issue.

But gee look a the fuel economy!

go the 140. it weighs slightly less, is basically the same as the 115 tuned up and probably won't cost that much more to purchase at the end of the day. as for running costs well i thought they'd be identical considering that they are the same basic motor.

probably the wrong section to post in, but, a 115 or a 140 on a Viking will not be a slug, 2 stroke or 4 stroke or any other stroke for that matter, the only time that would come into play is if you are repowering close to the minimum requirements, you will have more than adequate power, and as mentioned, if the 140 is the same weight, then that is the Motor for you (I reckon) unless the cost is a whole lot more.

Mate I would say the 115 would be more then adequate for your needs you could even consider coming back to a 90 check out the spec plate on you hull and have a look what the max hp is there may even be a recomended hp on there. Also talk to some people who own similar size seafarers and ask them how their donks go. I know I see a lot of them around here with 70-90 hp donks and the ones with bigger motors then that look to hang low in the stern at rest.
as for the 4st- 2st question don't the 4strocks have more low rev troque meaning they should jump out of the hole quicker?

Well probably being a 20 inch shaft the big four stroke with 2 people down stern the motor will have water wasing around the cowling seal all the time,i would recommend a 2 smoke for this boat. Podding it to 25 is the way to go, this is a v19c that is having a 225 going on the bum. cheer...jim

115 4stroke on my 17 haines does the job nicely, you dont need any bigger. does over 30 knots WOT, holeshot ok

my old man just got a mako craft, 445 and he has a 60hp 4 stroker on it, and it is slow out of the hole, compared to my boat with is bigger with more power, but my 2 stroker almost leaves the water when you get up it. but in the end, we will all end up owning 4strokes the way things are going. 2 strokes are banned in NZ as far as i am aware. it wont be long untill we follow suit.

I have always been told not to over power your boat as the torque in the engine can destroy your transom. Particularly in glass boats.

Stick within the recommend hp to avoid Bretty J issue, but go for as much hp as possible. It does not mean that you have to use it, but some times it is required, and you willbe glad to have it there, rather than regretting not spending the extra 1000?

it depends on how your motor is trimmed.
ive got a few mates with 4 strokes and they get up and goin very very quikley.
just as fast as a 2 stroke.
