Rest here for a moment in my little corner of motorhead insanity :-)
I built this site on WIX and aquired "unkiemotorhead.com" while on vacation in Hawaii in Dec 2019, because my Unkiemotorhead's Skunkwerkz site that's been up on earthlink for 15 yrs or so was seconds away from being taken down (obsolete web tech being retired) and because I decided that since a few relatives, friends and acquaintances still enjoyed passing through here from time to time....maybe a few AOMCI members pass through here occasionally as well..... I should build this to keep the unkiemotorhead web presence alive. So here tiz... Similar content as the earthlink site, but somehow different. Older. As am I. And a kickback vacation outta town is the only time I can imagine devoting to an effort like this. So far this build has been entertaining....though not always optimum. WIX is buggy and is missing some features I think it should have.
Can you believe that "unkiemotorhead.com" was still available? Think of all the unkimotorheads there are in the world.... YOU might be an unkiemotorhead.
I hope you enjoy your visit. :-)

- Each image window that opens when a thumbnail image is clicked includes a spot for my remarks...I've added just a few for starters.

This is a Karelson/Hoban boat I bought as a slightly safer version (180lbs, less aero lift) of the 150 lb Sorensen D boat presented further below. Same Lloyd Mize expansion chambers sometimes, or megaphones (provide the audio in the videos below -turn your volume up!), and any of my 44 mod blocks. Rock solid at mid 80s, which seemed a lot safer than walking around near 90 in the smaller lighter Sorensen. Look at a few photos carefully and you can see all the way under the boat to daylight out the back...."aired out".
Part way into this vid you can see & hear the motor start breathing better and accelerate
Provided for the 4cyl open megaphone noise
Got this F Pugh hydro to explore a 700cc Konig (that we built but never got running running right on the boat - fear and good sense probably held us back as it should have...who needs to go 110 in something like this? Yeah, I do, I know. But I digress...) and larger motors for the sake of art. Big, safe boat at moderate/slow speeds regardless of water conditions. It has now moved on to Matt, and the next generation of motorheads in Southern Oregon.
This is the Merc 800 on Wayne's Hubbel overdrive unit. Wayne's unit, my Merc 800 build, our joint project.
Wayne's work setting up the lower unit involved having the tapered propshaft welded and ground to a cylinder in the prop area to fit 11/16” w/1/4 shear pin props we got from DeWald. Lower unit rebuilding was a wonderful exercise in hidden snap rings and obscure bearings. :o) Yikes! But as of 2/13/04, it was rebuilt! Worse than building double-pinion SST120 units Wayne sez
25% overdrive 90degree model is that built for use on runabouts according to those we spoke with at the DePue Pro Ntls in 7/03...apparently the early 1960s OMC Starflight hydro kilo record units were 96 degree or something like that. If you need help understanding how to rebuild your Hubbell overdrive, Wayne is now DaMan!
Check out Uncle Wayne flinch when he zaps the throttle. :o)
During the hours spent trying to get this powerhead to run, we learned several things about the 800, and about setting it up to run backwards to accommodate the Hubble unit which has the propshaft gear in front of the driveshaft pinion. No way to find racing props that rotated backwards....so why not make the motor run backwards? That's what we said...
It starts best with the butterflys closed!!! Yup. The little holes in the butterfly upstream of the three small fuel ports in the side of the carb throat will dump the fuel only if the butterflys are closed. Squirt the reed cage full of fuel, close the butterflys, tap the starter, and it’ll light. I bet it lights in ¼ of a rev, it’s that quick. If the butterflys are open, no deal. That solved the no fuel problem.
Second, couldn’t get it started initially since the timing light was reacting to adjacent plug wires as well as the #1 cyl wire, so after going through all that carefully by starting the whole process over with Uncle Wayne, we got the timing and the plug wires correctly set up. Provides really crisp response as it should, based on Wayne’s considerable experience with SST120 motors and what I’ve seen with motors set at max advance. Timing is set at 18 degrees BTDC (running backwards – counter clockwise). This Thunderbolt breakerless magneto runs better forwards than backwards, but it sure runs fine backwards! Tested it on the Bridgeport mill counter clockwise at up to several thou rpm and it’s fine. Started and ran fine here. ANOTHER TRICK…..this is the first one of these mags I’ve dealt with, and we learned to use the 0.077” surface gap plugs since the large gap provides a HUGE spark relative to a standard config spark plug. Yeah, I think it should work fine on a standard plug, but the ignition was designed for surface gap, and it POPS KAPOW with a surface gap plug, so we changed over to surface gap. Weird. Those of you who know these ignitions were aware of that already I’m sure……this is my first, so I struggle.
The light flywheel and small rotating mass of the drive train makes this thing grab revs RIGHT NOW when we crack the throttle. Hoo dahh !!!!
Merc 800 'lectric start powerhead is used on this unit, and is similar to the 650 art motor, 'cept MORE CUBES! This looks tall 'cause of the height of the Hubbell, the position of the moter mounts on the F hydro relative to the bottom of the boat, and the need for at least SOME driveshaft length (mebbe 4"?). Believe me, if we chould have made it shorter, we would have. We've rebuilt the SST120 starter which we need to start the motor to run backwards
A Stock Runabout (with B motors)
One of two small outboard boats I still have - the Sorensen in Idaho, and this A stock boat built by Steve Wilde....a little too much lift for a B/25 motor, but hooo does that make it an entertaining handful with B/25 motors.
We run this with a B Champion I have that was built for me by Cooper Jess, and several converted 20H and 25ss motors that I built.
