I finally got my skinny water rig out for a test run this past weekend. I got a great deal on the layout boat/blind/trailer, but I knew the 9.5hp outboard would'nt cut it for hunting around here. I was on a very tight budget and could not touch a 6.5hp longtail for less than $1500. That led me to the eBay SPS kits... After a little research on the kit and seeing how easy the honda clone harbor freight motors were to mod, I was sold.
I picked up the Predator 212cc engine from Harbor Freight on sale for $79. I added the 2 yr replacement warranty for $20. I know it's a knock-off, but it's pretty well made. I was impressed.
I decided to do the basic stage 1 kart mods before I ever fired up the engine. I ordered parts from OMBWAREHOUSE and NR-Racing. I removed the governor, re-jetted the carb, installed GX140 emulsion tube, advanced timing 8deg, replaced flywheel with OEM GX200, installed 18lb valve springs, high flow air filter, and custom header/exhaust. I had zero experience modding small engines, but there is a ton of info out there on the karting sites and forums. Mods finished, ready for the mud motor kit.
The kit was shipped with a chrome tiller handle and chrome coupler housing. The transom and brackets were turquoise... I sand blasted, primed, and painted everything and installed everything on the boat without any major problems. I also added a small digital tach to help tune the engine/prop combo. My biggest gripe for now is the throttle set up. I'm working on a brake lever/squeeze throttle, i just need to get it all together.
This thing handles well, not a lot of tiller torque. The whole motor assembly weighs less than 70lbs, so it's perfect for a small boat. I hit just over 15.2mph at 4250rpm with just me. My buddy jumped in and we were cruising at 12.5mph without a problem. The kit came with a 6.5in prop, but I have 7in on the way to compare. Here are few pictures of the whole rig.
I found a little bit of mud, but no enough to really test it out yet. Hoping to do that in the next few days. I have high hopes for this season with this set up.. With the boat blind on I think it's going to lethal!
Got a PM asking for a video of it running... Here it is. Sorry about the lighting!
