Re: Squirt jet powered first water run

I missed this too... and just posted a question about the 500 Yamaha engine and drive last week!

What kind of speeds do you get with this craft?

Any suggestions on mating the Yamaha running gear to the Squirt plans???

A boat racer, who may need to do something as he ages besides race!

Re: I need some help with Terms.

Loop charging involves more than one transfer passages from the crankcase to cylinder in a 2-stroke engine. Usually three intake ports and corresponding transfer passages introduce the fresh fuel mixture into the cylinder in a manner that forms a "loop" to more effectively push exhaust gases out (sc...

Re: New Outboards for a Squirt 11'?

Mark 25 is one of the best two-stroke boat motors of its size around... parts are still available and it just looks "right" on that boat.

Re: looking to re-power the runabout

You might also want to look at a Tohatsu M50D2 three cylinder... 42.5 cubic inches, loop charged and very similar in performance to the older Mercs witho...
