I made my ride plate out 1/4" aluminum plate also. I used 1/4" plate because the cast stock ride plate is brittle. It's pretty common on standup skis to bump the bottom of the ski and lots of people crack stock plates even on sand bottom surf riding. I bowfish below dams on rivers with a lot of...

You laugh, but a friend "helped" carry the rear of one of my skis with me to the water. I noticed it didn't seem right and found he had carried his end by the steering nozzle and had broken it :( I would SERIOUSLY add something very substantial to mount the pump mounts (front and rear) to...

Is that the way your pump is setup when everything is all installed?

That looks good! I presume it's a 144 since that looks like an OE wear ring??? If it uses props that fit OE pumps (unlike Skat pumps that require magnum props), you should be able to find one that's right on for your boat. If the prop is right for an FX-1, it may be shallow for your boat, but...

. When you say you have flow, but with steam or air mixed in that almost always means your head gasket is leaking. More times than not, you can replace the gasket, but instead of dry, use a fairly thin layer of 3bond 1211 on it (both sides). Yamabond 4, Suzukibond, and Hondabond used to be...

You're right on with screen size. I've got a new 3/8" barbed fitting strainer out in the shop if the OP wants it. Just P.M. me your address and you can have it. McMaster Carr has stainless filter screen material in many mesh sizes in small pieces if you wanted to roll a piece yourself with a...

The strainer shouldn't cause any issues. A big concern with inline strainers to keep in mind is that they supply clean water ONLY when clean. If you use one in sandy waters you may find that you have to clean the often. If you don't realize it's clogged, the filter can actually be the reason...

Here's a link to the Riva pump strainer. It's made for 155mm pumps, but I think you could either adapt/fabricate a standoff to make it work on the 144 pump or make something similar. https://rivaracing.com/i-17284030 P.S. That's the 90deg brass barbed fitting I mentioned in the dual cooling...

A smart thing to do is to run dual cooling. There is a round protrusion on your pump 180deg from where the stock cooling line connects. Drill a hole sized for 1/8" NPT (all the way through). Use a brass 1/8"NPT 3/8" 90 deg barbed fitting. Use the through hull fitting that was used for the...

I managed to drag my shooting stand(about 45-50 lbs)over and take a few pics. As I said earlier, it's NOT any sort of masterpiece. However it did work well. The male pedestal mount on it's underside inserts into a standard casting pedestal which inserts into the female pedestal mount on the...

Here are a couple of pics of my homemade stick steer. It's just a wedge made of PVC board made to attach to the gunnel. The "stick" you see coming through the slot is the steering stick. The lever on the side is a multi detent trim lever to get the nose out of the water in wave trains and to...

If you ever do have a lean runaway, pull the lanyard and give the motor full throttle. It's hard to make yourself do that, but it'll kill the motor every time.

OK, I finally got around to taking the best pics of my pump/prop/rideplate/intake grate setup that i could. It also shows the steering and trim system. I also took a couple of pics of a stock stator section so the differences can be seen. Keep in mind The pictures of the mag pump are taken...

I'll do my best to get pics of the mag pump and pics of an OE stator so the HUGE differences can be seen. It may not come out with great detail since the exit, steering, and trim are installed, but I'll see what I can do. A mag pump is truly a thing of beauty. :)

I've been lurking here for a while and only recently made any posts. I apologize for making so many in only a couple of days. I really don't think I know it all and am relatively green to the whole jet jon thing. I've wrenched on just about everything imaginable, so I have a decent feel for...

You shouldn't have to change anything. Essentially, if you have a boat that an OEM Yamaha 144 pump bolts into, a Skat pump made to be used in place of the OE 144 will bolt in with no mods needed. Even the setback version bolts in directly. It just requires a 1" longer driveshaft. Normally a...

I always used 140's, but was curious about how a 144 would work. A friend of mine was sponsored so I was able to get a complete setback 12v with Skat driveshaft for a bit under 1G. After playing with it for a summer, we all agreed that it worked about the same as the 140. Our base of knowledge...

With all my skis I've always been fanatical about rinsing out the pump after beaching and have managed to keep my pumps and props really mint. The jet Jon will mainly be a bow fishing boat also used for bass fishing. Luckily the rivers I bow fish are rivers I've paddled for years and most of...

Polaris are a bit of a weird kind of boat. They made some REALLY good boats and some REALLY bad boats. Actually, I should say that about their motors. I've only worked on a few Polaris boats and they were all 650 & 750 triples. They made really good power for the cc's, but had a number of...
