Super Jet My First RN Build - Complete rebuild, shorten, and rocker!

But Boats fall into that category, or do they just look the other way on that? I had friends that use to wakeboard he stretch from the Swenson house to 3rd street launch in high school.
Boats aren't part of the 150ft from shore, other boats while boating or diving bouy's are all I found in the DNR boating guide. \
In any event, we totally jacked Jeremy's thread, lol
 
Yes, I am referring to the river in thief river falls. I've always been told that they do not allow pwc's on the river per city ordinance because of issues with A/C testing on the river back when they made pwc's.


Others have also said that its because its a no wake zone 100-150ft from shore. But, you see boats cruising up and down the river all the time. Including when guys I knew use to wakeboard on the river in high school. So that's what I meant when I said that the DNR and such must just turn a blind eye when it comes to Boats vs pwc's.

Ohh alright, I thought any vessel was apart of that rule.

And yeah sorry, thought I was just asking a quick question. Didn't mean to derail your thread bud!
 
Well its that time of the year. Christmas is over with and its the perfect time to fix everything I screwed up rushing to get my ski done for Summer 2015 (or Fall should I say).

So last night I pulled my motor out and so begins the teardown to see if I can find anything wrong as it was running quite horribly before I put it away for the winter. Long story short, ran it at Sortie at Hok Si La Park in August and it ran most of the time OK once I figured out I was missing a low speed jet in one of my carbs lol. Before I put it away it was having bogging issues after high speed running, idling poorly, no carbon on the piston crowns (no wash), didn't seem to matter what I did to the jetting it didnt fix it. Either won't idle or wont rev or both.

This was my most recent carb settings and I'm looking for advice on what to try next: 110 Pilots, 115 Mains, 2.0 N/S, 115g springs, 30-32psi popoff tested, ~1.5 turns out on HS, ~1.5 turns out on LS.

Been contemplating going down to a single 44 to make things easier tuning-wise.

Another side note, there was a god-awful rattling/banging noise inside my engine compartment when running, scared the hell out of me the first few rides as I thought there was a mechanical issue with the motor, I'm hoping its just the waterbox hitting something.

Anyway, once I figure out the motor and banging sound, its time to tear down the whole ski again, rip off the turf, strip out the pole and reinforce it, install dual pole breathers, and begin the torturous process of sanding, puttying, repeating, then sanding priming, and repeating until I am happy with the finish. Once prepped it will be painted Satin "Camaro Synergy Metallic Green" with black turf. If there is time I hope to attempt a custom non-breathing low profile carbon hood.

Updates and more pics to come as I progress.
 
Update: Cylinder walls were scored and pistons touched the domes (even though squish measured correctly when I put it together). Either way the motor was bored out 84mm, honed, new Pro-x pistons, rings, wrist pin bearings, etc. Bolted the motor together with the new @JetManiac ADA head and girdle kit, leakdown tested to 10psi and passed. Compression tested @ 195psi/hole. :) (That was after 120psi scare by a Harbor Freight compression tester lol).

Anyway, found some light cracking underneath the extended rails, most likely because I didnt run carbon down the bottom deck. Spend a good two weeks stripping the hydro turf, sanding off the primer from last summer, body filling, adding an edge for the turf to butt up to and sanding the rails and bottom deck to prep to add a larger fillet where the rail meets the bottom deck and reinforce with either 1208 or a few layers of carbon. More pics and updates to come :)

OK so here's the weekend update! Happy with the progress :)

First I reinforced the rails underneath and along the bottom deck. I was really worried because I saw cracking after only minor riding last summer. So I made a super concoction of cabosil and chopped glass and made a large fillet in the corner between the bottom deck sides and the rail. Before it had a radius of about 3-4mm and now its about 10-15mm radius, should reduce the stress concentrations in that area. Then i laid a layer of 1208 and topped it with a layer of 6 oz carbon.

As for the pole, I'll preface by saying I can't take full credit for this design :p.. I basically followed my buddy @Mud-Nut through his RN build ( http://x-h2o.com/index.php?threads/superjet-project-rs.156775/ )and added a few of my own tweaks and wrapped it in carbon :)

Yesterday I decided to focus on finishing the pole which took all day Saturday and Sunday. Saturday I did all the prep work sanding the castings and pole and foamed in the 2 breathers.

Ready for glass!

From here I apologize I was in such a rush with the epoxy curing quickly that I didn't stop to take pics during.

First I cabosiled and riveted the ends on.

Then I filled all the big gaps, tight corners, and the extra holes for the cover that is normally on these poles. I basically wanted it to be super smooth and easy to carbon over.

I ended up doing 1 layer of 1208 on just the pole from casting to casting (not on the actual castings). Then i cabosiled the spots between the castings and the first layer of 1208. Then I did a full layer of 1208 going over the entire pole and about 2 inches over both castings as well as down the entire front side of the lower casting. After working out the bubbles I laid a final 6oz carbon layer cause I wanted visual carbon. Again no "during the process" pics but here's the final result, will need some cleaning up and clear coat afterwards:

Quick update: laid carbon on the sides and the nose/pole bracket area. Trimmed the excess carbon. Drilled the holes for the pole bracket and mounted the pole to mark out where to cut the hood. :) starting to take shape!
