How much money to trade in a 01 Yammy 90 to buy and install a similar 4 stroker?

[TSCTSC]

Just wondering if it is worth the cost to change a 2 stroker to a 4 stroker. Am actually very happy with the boat but I guess I just want to make it better. Not easy to find a totally ideal package if you buy used. How much money and trouble would it be to trade in the 2 stroke, take it off, and then buy a 4 stroke and put that on? Thanks. Approximate costs and highlighting of potential troubles that could happen with this would be appreciated. Thanks. Mine is a steering console, so I guess the main issues are running the cables and the fuel line to the fuel tank.

If you've got a perfectly running 01 2-stroke I wouldn't even consider going through the time and expense of putting on a 4-stroke at least until the 2-stroke starts acting up.(that should be in about 7 to 10 years) Unless of course money's not an issue.

I recently replaced a 1999 90 HP Mercury 2 stroke with a 90 HP Evinrude Etec which is a two stroke but has 4 stroke qualities. I also researched 4 stroke motors and considered going to one.

It cost me about $5000 to upgrade to the new motor including the trade in of my old motor. After having the new motor I can say I do not think it was worth that much to make the switch. I like my new motor but $5000 is a lot of money.

Some other things to keep in mind: The 4 stroke will be quitier and smell less than your old 2 stroke but it will not necessarily troll slower. Yamaha has the new 90 4 stroke that allows you to dial down your RPMs which will allow you to troll slower but generally speaking the 4 strokes troll faster than 2 strokes. You will probably lose some hole shot power as well going to a 4 stroke as compared to the two stroke. You top end should be similar if you use a comparable prop to what you have now.

I would also consider the Evinrude Etec if you are looking for a 90 Horse. As I mentioned earlier this is a 2 stroke motor that is cleaner than 4 strokes and runs very quiet and doesn't smoke. Also consider the Suzuki 4 stroke. Bass and walleye boats magazine did a 90 Horse shoot out and the Suzuki and Evinrude Etec tied for the best motor.

Thanks for input. USD5000 is quite a lot, but having said that you went for a top of the line model which is Evinrude....my envy. So I guess that would be more. But would a similar Yammy 4 stroker be significantly cheaper? Do you think 2000-3000 USD is reasonable cost?

The Yamaha will not be any cheaper than a Evinrude. Maybe a couple bucks but not enough to make a difference.

Yamaha, Suzuki, Honda all make good 4 strokes. I like Yamahas.

The E-tec sure sounds like a good motor. If half Evinrudes claims are true they have one heck of a motor there. I would wait a year and see what people are saying about them then. Thats just my opinion.

I know you cant go wrong with a Yamaha in the 90 or 115 4 stroke. I have the 115 4 stroke and love it.

Just did what you are contemplating. Went from a two stroke to a four stroke- 50 hp power, evinrude to honda. Cost was about 3 thousand, best move I have made with the boat. Really like that honda. I guess it is what you can afford. I know honda's troll down nice, a buddy of mine has a 75 hp and we can run plugs behind that at about 2.5 mph., that is on a 16 ft pro V.

Another thing to consider is how much you use it!!! I just filled my Yarcraft and the bill was $100. This will last a week or so for me. The difference in gas would pay for the new motor in two years for me!!! And I would have a new motor!!!!!

Suzuki is not making motors for Johnson starting with the '06 model so you may be able to find somewhat of a discount on a Johnny 90 4stroke in the '04 or '05 models. I have this motor and it's a dream.

Crystal Pierz may be your best best for finding this motor. When calling around, CP seemed to pair up their boats with the Johnson. Maybe a discount awaits.....
