2 or 4 stroke.

[pnut]

i have a 14' aluminum boat with a max of 30 hp engine that can be used with it. here is a pic

this is similar to the boat i have. but i have a wooden floor to walk on so it is a bit havier. im looking to buy a new/used 25 hp motor to replace the old motor (15 hp) that as been give us a lot of problems this summer. <br /><br />what motors would you guys recommend for this type of boat. should i be looking for a 2 or a 4 stroke. thx

Re: 2 or 4 stroke.

Looks like a perfect application for a nice 2 stroke JohnnyRude 25 electric start, pnut. They have been the standard for 14' tinnys for 50 years.<br /><br />On the other hand a late model Honda 25 or 30 would be nice, economical, clean, quiet, fairly light state of the art power.<br /><br />If you want maximum value for minimum bux, find a good, post-'64 JohnnyRude 25 or 30.<br /><br />If you can stand the cost, a new Honda 30.<br /><br />Good luck.

Re: 2 or 4 stroke.

Just some thoughts:: Most of the 4 stroke motors are fine motors and as stated are clean,quiet and<br />get good MPG.But there are just too many moving parts that will require both routine adjustment and repair over time.And then there is the weight issue.<br /> We are talking 6 moving parts on a 2 cylinder 2 stroke compared to over 20 on a 4 stroke.<br /> I think Evinrude is building an Etec 30 hp 2 stroke That meets all inviromental requirements.<br /> And there are other companies working on this type of 2 stroke as well.

i will agree with you about the weight issue. but i ahve check all the outboard complanies and none make 2 stroke 25 hp motors (i could be mistaken)but i didnt see any. second i not worried about more moving parts beaking down. yr car has a lot more moving parts and still runs everyday 7 days a week. in the long run maybe like 7+ years from now things will wear and tear. which is something that will happen no matter what, 2 stroke or 4.<br /><br />so far i found that honda, Tohatsu, and mercury have 4 stroke 25 hp motors that weight in at about 70-72 kg. compared to johnson or suzuki what weight in at over 90 kg. <br /><br />has anyone had experience with honda / mercury / Tohatsu motors.

I have a 9.8 tohatsu 4stroke. They are fantastic motors. Do a little searching around here and I think you'll like what you find

pnut, please use the search button on the top of the page and you will find more than enough info on the differences between 2 and 4 strokes.<br />It will not only help to make you an informed boat user, it will also tell you why you should never ever compare a car engine with a boat engine.

Re: 2 or 4 stroke.

if your looking for a newer engine mercury made 25 hp 2 strokes from up to about 2002-2003 i think.

It all boils down to what you want to spend. Both will do a good job for what you want I would say.<br /> Good Luck with what you decide. Tim

I second JB get a carburated 25 Johnson 2 stroke. You should have no problem finding a good used one a couple of years old. Anything simular in a Mercury will be good too.

Re: 2 or 4 stroke.

I have a 20 HP Honda 4 stroke (rope start) on a 14 ft Lund. It has plenty of power. I looked at the 25 HP Honda 4 stroke too, but there was a significant weight and price difference.

Iboats has a bunch of newer 25's 2&4 stroke.
