I no longer have a boat for this engine so up for grabs is a CMB 21RS engine and header.

Like new two tanks of fuel put through it to begin break in process. The CMB .21RS marine engine features a new crankcase with larger flow passages and new design Piston/Liner. with induction port, stronger conrod, modified cylinder porting, new single plug cylinder head and Red water jacket.

Bore: mm 16.33

Displacement: cm 3.49

HP/RPM: 2.9/35,000

Stroke: mm 16.77

This setup sells new for around $475 plus taxes.

I will let it go for $375 shipped anywhere in North America and I will throw in a used AB20 Parbolic pipe.

Thanks

Hi Walt

Sorry both engines are sold.

PS

That Frank Orlic CMB 45 that I got back from you is wicked fast in my PT Sport 40. I love it.
