3.5CC OR 7.5CC OUTBOARD???
Ok guys straight to the questions, should I spend my money on a "new" K/B 7.5CC outboard to reach between 38-44mph on a tunnel or buy an O.S to reach, I don't know what speed?? I would be more inclined to "slight modify myself" the 7.5 cc. Who is James at O.E.R? does the sell "new" modified O.S engines? It would be nice to see a wood 24 inch dumas or a VS1 with a "factory modified" O.S 0.21..... ( currently I have a TS2 with a slightly modified (just sleeve and crankshaft) regular k/b 3.5 cc and it will do 35mph all day, i love it, super reliable). Just looking for a second toy....

First the "Disclaimer:" I am a consultant for AquaCraft.
Yesterday, I tested the recently released AQ VS1 3.5 tunnel hull with an stock O.S. 20 OB. It was easily doing 45 mph in a small pond. You don't need a modified O.S. 20 to run close to 50 with the right boat.

hmmm sounds good, on a 0.21 size engine it's not that easy to reach 45mph. What nitro and prop where you using? Thanks.

OK, what's you're ulterior motive? Any plans of racing? If so, I'd stay with a .21 OB tunnel as the .45/7.5 class is slowly dying off for lack of engines.
The VS-1 isn't really made for a modded engine. You'll have to wait to see if Mike and the crew at Aquacraft are going to come out with his Nemesis for that.

Thanks Jerry, mind telling me where i can find 707 specialties? Sounds like a preety easy setup to reach over 40mph. Thank You. I'll be happy with anything over 40mph consitent! "not falling off pipe" etc.... The ts2 with the stock k/b is just not competitive in the 0.21 class.

Thanks Jerry, I ordered a VS1, O.S engine and a prop from Joe. Please help me set up the boat similar to yours, I have "heard" that i have to remove the head shim from the O.S. engine? Thanks! And just advise me on anything else that comes to mind.

RE: 3.5CC OR 7.5CC OUTBOARD???
So is 7.5cc really dying. I was thinking of cruising ebay for a K&B 7.5cc pro outboard or maybe stepping up to a new Rossi 7.5cc, but if its a dyin... I just like to mess with these things but I don't want to be in the slow lane. My hull is also old fashioned so it might be better to try anew with another combo.
