[Fast Fred]

for real, cuzz any thing else is crap

so check back

[Fast Fred]

anyway, finger ports, why finger ports, well the dif' between a 150hp and a 200hp for the most part is, ya finger ports ,so we'll take them.
machined finger ports are vary nice, done by hand they can be every bit as nice. most important is the rings, we don't want to upset the rings. it's easyer to cut them(ports) before the rebore, that way you can clean up any slip ups you mite make. you want the ring gap to run about dead center in the finger port. or on the bridge of cyl wall in between the intake ports.
take the piston and mark the ring gap pins to the top on the dome, then put the piston on the rod, with no rings on it, bolt it to the crank, mark the cyl on top ware the pins sit, then at BDC make a mark.

i'll make some shots so yas can see it this far, then i move onto whats next.

the "rubber ducky" , here in california (northern) holds the 2 man runabout world's kilo record at 112 mph. With only (if i have it right) a Rossi 350 C C motor. As far as i know ,this is the the fastest outboard runabout , regardless of engine size . (2 man ) - Driver- owner Terry Klemm.

Terry was using a Rossi 700CC or so engine. Sort of a custom I believe. I looked it over real good at DePue this year because he was pitted right next to me. Very Cool rig. At least the engine he had at DePue 2007 Pro Nat's was not 350CC.

.................................................. ............................ Sorry, you're WRONG. I was there that day, last year, and talked to him . He told me , or , like you , i would not have thought it possible with such a small motor . So , unless i was told a LIE, it was that really small motor . For me , it's hard to believe anybody went that fast IN A runabout , with ANY SIZE motor . But, the clocks don't lie .

I want to know what boat he was using? was it a v or a tunnel
