If you were closer I would loan ya one of mine, or better yet pace you in my FLATS boat. Had it up to 59 a couple weeks back with a 1/4 tank of fuel and 2 people on board. Although my girlfriend pretty well said she wouldn't let me go that fast again in a boat with her in it. Got her attention when she seen the speed and I launched off a wake of another boat:you:.
 
that merc auction is ending today in 1 hr .. price is up to $830 with 7 bids. hmmm... compression worries me though on that one cylinder.
 
I'll let you all know if a V20 with a 225 Evinrude will do 60 real soon. Right after I move, rent out my old house, fix the transom on the boat, and get it all rigged.... O.K. maybe not too soon, This list is depressing me.
 
that 150 merc went for 1236.00 .. too much with that miss and those compression numbers ..

search is still on.

my boat right now will do nowhere near 60 .... actually it will not even do 15 :) bought it with a blown sea drive.

60 would be nice .. i am a bit of a speed demon, at least on the ground .. but 40 on the water seems fast to me.

if the guy with the yamaha 200 replies back to me, may go look at that one.

looks like batteries to front is a good idea no matter what. or i can sit my fat @$$ up there and let the wife drive ...

on second thought .. skip that .. bad idea.
 
I think you made the reight choice on that MERC, and if you get the YAMAHA I think it would be a good choice. Just remember to keep it light. Unfortunately the lightest option is also the thirstiest option. An old 235 JOHNNY-RUDE would be light and powerful, but it earned it's reputation as the 2 thirsty 5 for a good reason.
 
Therm is right.

I can tell you from experince my 235's was thristy! 27 gph at WOT. My 74 CC ran 43 MPH with that motor just like every one else (sorry couldn't quite get 60!!!). The only outboard that I know that is thristier is what I'm running on my other boat!, a 250 V8 Johnson! 32 gph @ WOT - but it will push a old and heavy 25 Aquasport CC at 42 MPH.

Kamikaze
 
Therm I will have to agree on the Yamaha. There are always so many people who say a 200 is too much and I will disagree everytime. I have a 1990 Yamaha 200 and in calm water I can do 47Kts or 56MPH WOT. That being said I rarely have to cruise anything above 3100 rpms for an economical cruise and still get to where I am going fairly quick. I have been on only one other V-20 and it had a 150 and that would be a bare minimum in my book.
 
Plus the YAMAHA 150 and 200 are the same weight in the early years as they are the same displacement. Mid to late 90's they upped the cubic inches of the 200 to the same as the 225/250's.
 
now i have another dilemma. i got a response from the guy selling that 1990 johnson 225. the ad states rebuilt powerhead with 100 hrs on it. 25" shaft .. controls and wire harness included.

this was the one that said "easy on gas" :) . asking price is $999

my boat is an 85 center console .. my max capacities decal is missing. someone posted that my boat is rated at 200 hp max.

i also read on here somewhere that this motor would fit my weight needs.

what are your thoughts .. i know some say it is too heavy, some say it is not. the other motor i was looking at is a 92 yamaha 200 with 300-400 hrs of freshwater use (?) power trim tilt/oil injected and no controls for $1600. the guy is hard to contact. does not seem real interested in selling it.

can i run a 225? is it much heavier than the 92 yammi 200 that you already gave me the green light?

thanks again
 
There are fellows here that know these engines well and know if the weight would be a problem motor to motor.
Just being a amateur but seeing afew things in my day I would say do not exceed the horsepower rating. Do I think the manufacturer was being slightly conservative, possibly. Do I think the hull when NEW could handle it, yes.
If you are insuring the boat you will of course make it hard to collect for any damages you suffer. Could there be other legal problems, not likely but possible.
The major reason I would say to not do it is, it is unnessasary, you may be overpowering a old transom, you be be adding weight to an undesirable if not downright unsafe level.
The question in my mind at least is why?
JMHO
 
all good points .. i guess some of these boats were rated at 225 .. i think someone said that '85 was 200, but not sure.

i agree, if the max for my boat is indeed 200, then going beyond that may not be a good idea .. even for 25 hp.

i have no doubt the boat could handle it, especially if some years were rated for 225, not sure what changes could have been made to the hull for this ... maybe no changes were made.

i would be worried that if something happened, i would be sued by some lawyer stating that since i have 25 hp more, that is what caused the accident.

i am not sure what max hp my boat is rated at.
 
Up to 85 was 200HP max, and 86+ was 225HP max. The main reason for the increase in the max HP rating was the design of outboards changed. Up to 85 there wasn't a lightweight alternative to really get more than 200HP out of an outboard. In 86 OMC came out with the 200/225 loopers. The big V6 loopers from OMC weighed in close to 475-500 pounds, and that YAMAHA is just shy of 400. This is enough of a weight savings to make a difference on a bracket mount application. You can always try it and see how you like it, but I think WHATKNOT has a good balance on his with his YAMAHA he has. The extra HP isn't so much an issue as the extra weight that the big JOHNNY-RUDES pack. Look at it this way, MJ's SEA OX is a beast of a boat and he has a 225 EVINRUDE on it. Now consider the difference in balance and size, yet hanging that engine just as far back with just as much weight. That is a BIG difference in balance.
 
great info ...

did not know there was that much diff in weight between the yamaha and johnson .. that much weight would make a difference, especially with the bracket application.

all makes sense. thanks
 
on a side note....

where can i get a replacement max capacities plate for my boat? can you get them from wellcraft?
