    Does the dark side really have cookies????

    I’ve always been an aircraft/GPU guy but I think if I was to get or build another boat it I think I am going CM and gear box. I don’t even know where to start with a motor. I want something carbed that makes good power but not super hopped up and unreliable on a 13-6 aluminum hull. Not sure...

    So those that have been following my recent posts I finally decided to start collecting parts and do a 470 conversion to my 220. So if my holley is running good on my 220 with a single mag and dome pistons do I need to do any adjusting putting it on a 470 conversion?

    I am planning on doing a 220/520 build and thinking about going the GTSIO route because of intake clearance issues with my rigging. What can be used from a 220 intake and is a Holley 500 enough carb?

    E225/520 build

    I plan on building/having a motor built in the next year or two. I don’t think converting my 220 is worth it and it looks like a E225 would be the easiest motor to drop into metal work. The biggest question I have is should I go to a builder and let them find me a bottom end , core motor, or...

    Lucas oil additive raising oil temp?

    So last oil change I put a quart of Lucas in my 220. Mind you this is after I redid my hull, painted the rigging, replaced oil and fuel lines, and re-wired the boat. First time out noticed oil temp was a little high and she was definitely running rough. I figured that was just because a mix up...

    Steering connecting rod for bell crank steering

    I want to make a new connecting rod that goes from my steering rod to my bell crank. It appears to me that whoever made it before just blazed a bolt into the end of 1/2 conduit to screw a heim joint on. The 1/2 is just too flimsy. Either way I need to know what kind of bolt is safe to braze...

    E85 in an aircraft/GPU?

    I read and interesting article saying that E85 has a higher octane rating than tradition pump gas or even AV Gas 100LL. On top of that there are E85 conversion kits available for Holley carbs. From what I've read there are some trade offs.E85 is 25% less efficient than traditional gasoline so...
