Re: 16hp duramax w/ Electric Start Feedback We've built 2 mudmotors with them
Decent for the money. No mechanical issues but the bolts and covers are soft material so u can strip a bolt off fairly easy but again no mechanical issues at all
The last engine I bought was a carroll stream. It is also a honda clone and possibly built by same people but fit and finish is much better but it cost slightly more. Google carroll stream engines to compare

Re: 16hp duramax w/ Electric Start Feedback I have a 1436 that mine is on and I get a little over 20 MPH with it with two guys in it. I did have the bracket for the ignition break

Re: 16hp duramax w/ Electric Start Feedback surface drive or longtail on the 20 mph speed ?

Re: 16hp duramax w/ Electric Start Feedback Must have been surface drive cause I can barely hit 17 empty?  I just built two longtails with the duromax this past week and I think they are a pretty good engine, When I pulled them out of the box I thought holy crap cause they look HUGE! not bad when you bolt em up though... I run a durostar on my longtail and have not had any problems with it. Heck for the price you can get em at i don't think you can complain too much if they run.

Re: 16hp duramax w/ Electric Start Feedback ^^^
It is a surface drive spinning a 10X8 prop with a 1.5:1 reduction. It was actually hitting 20.8 at about 3950 rpms. I was holding the gps.
Just make sure you do not over-rev these engines. If you play with the governor spring you can get them to turn 4600, but don't!

Re: 16hp duramax w/ Electric Start Feedback we had to weld up the tabs on the ignition box also, very soft metal
