Anyone know of the availability of a titanium rod for a K&B 7.5 ?
Terry Keelly may of made some but if you can find a RPM rod they are good. What are you building as you are going to spend $$ on all the parts ?
I have been out of boating since the early seventies. When I raced a White heat 4-60 with a 65 Rossi , a Don Pinkert rigger with a Super Tigre 65 and my last boat a Crapshooter with a Super Tigre 65. I picked up this new K&B 7.5 relatively inexpensive and am going to try a Phil Thomas Stealth 45. A new CMB , Novarossi or Double Ace would be about $400 more than my K&B. I am also building Blazer Lauterbach and am trying to keep the budget down.
Run it until it goes KaBoom. Then you can hopefully get a newer one.
The K&B rods were ok. No need to replace unless it has one of the round unbushed rods. They were hard anodized and had no bronze bushing in the big end. Not sure if they were ever put in the 7.5 inboards or not.
It is very difficult to use any Titanium alloy as a connecting rod material in a miniature two cycle engine! If your interested, I'll explain why from actual experience.
I have one if still interested. It been In a box of parts for several yrs. Has some oxidation in bushings but scotch brite should clean it just fine. Was never used in motor.
