I run a wood Hotshot Sprint and a Top Speed 2, both with K&B 3.5 engines. Neither of them are piped, although one has the stock K&B barrel muffler some might generously call a tuned exhaust. I'm not a serious racer but, like everyone, have found myself ramping up over the years, looking for...

This is truly a stupid question and I apologize, but trust I can rely on this board's usual friendly bunch to help me anyway. I just bought a JR z590m steering servo on eBay but it came without the servo arm retaining screw. This servo has a metal output shaft. I tried a regular horn screw...

Has anyone seen one of these FMH kits up-close? Ebay: FMH Dolphin tunnel I'm not interested in getting one or anything, but there seem to be a lot of them on Ebay right now so it's only a matter of time before someone comes to the lake with one. I've never seen an outboard set up like that...

I'm sure others have already noticed this, but MECOA/K&B is now selling props and other accessories that seem to come straight out of the Prather (may it rest in peace) catalogue: http://www.mecoa.com/acc/marine/index.htm Whether or not you liked Prather's outboard stuff, this is fantastic for...

I'm a sport boater with a worn-out, 15-year-old, bone-stock K&B 3.5 on a 24" wood Hot Shot Sprint. I'd like to replace the engine and have the sense that the K&B SS is the best balance of performance, ease of use and cost. I'll also consider an OS or alternative. Please let me know if you've...

Changing bearings has got to be the toughest job on these things and I can't seem to find any clear instructions or recommendations on doing it. I'm sure this must have been covered lots over the years, but I've been searching the forum for a couple of hours now without hitting the nail on the...

I'm thinking of bumping up my stock black-carb K&B 3.5 to something like a wet SS, and hoped someone here would have a spare SS muffler, adapter and stock gold carb they'd like to part with. Also would be happy to hear from anyone who's done the same so I know what to expect -- for instance...

Running what I believe is an older, all-wood Hot Shot Sprint -- bought it several years ago, in pretty bad shape cosmetically, from a guy who had no idea what it was. It's been a tremendous fun boat for me ever since. I had great luck running a stock K&B 3.5 until yesterday, when a receiver...

Flex shafts are becoming harder to come by in my neck of the woods. I have been turning over in my mind the possibility of making them, or alternatively wondering if anyone else is already doing so. The flex shaft on a K&B 3.5 is, I think, 5/32" cable crimped to square at both ends. This...
