I did a type 13 budget build last year and posted in the GP1800 facebook group. It wasn't that bad to do once I got the mounting plate fabbed up. It ran dead even with my buddies ski that had the...

Perfect thanks! Same measurement here

Looking at re-pitching a solas 13/18 that was previously "custom pitched" by Deans. Right now the trailing edge is 5mm on one and 6mm on the other. Anyone have an out of the box 13/18 the can measure...

Nice! Same speeds here in SE Bama with same mods on my buddies GP. He's running the 13/20 and seeing what your seeing speed/rpm wise and I run the 13/18 with the same mods same speeds but around...

Good for hookup/bottom end and chop, not so good on the top end. I took mine off last year and went with a 13/18. Picked up 4mph and some cavitation on take off. I ride lakes so it really didnt...

What kind of RPM are you seeing? The 13/20 maybe holding you back a couple MPH. On a 13/20 dual prop and stage 1 plus with ribbon delete I was seeing 77-78mph depending on water, swapped to the 13/18...

Look at the modification requirements under each tune on the maptuner.

Guess I won't be rebuilding this one. 461821

No crack. It was leaking between the bracket and hull. I could fill the back with the water hose and look under and see it dripping down the bolt. Like I said it wasn't a huge amount but still...

Same with mine. It still leaked

Rode most of last year with the same issue before replacing the bracket over the winter. Only thing I noticed was water was entering the hull from that bolt/hole. Not alot but was noticeable.

Yes. I don't need to know how to take it off just wanted to verify its bad before I do all of that. I rebuilt the engine last year but can't remember if it spun one direction or both

Currently have no boost or throttle response after riding through two tanks of gas today. Pulled the supercharger and the one way bearing spins both ways so it's the clutch right? 32hr on the motor...

Yep. I was just curious as I have a maptuner now and not a key for this weekend.

Nope just the standard Stage 2 8800 tune. Non AGR Non ATR


No key fob came with the Ski when I purchased it. I even made sure they werent zip tied like most.

Not to highjack this thread but stupid question. I currently have stage 2 GP1800 and when my wife/kid ride is it possible to run the stock maptunerx tune with stage 2 mods? Its only for when they...

Just curious how in the world you got the nuts back on the tie down? It was bad enough trying to tighten the clamps on the exhaust

This^ Similar happened to me this weekend. Would act like it was cavitating but still run fine. Got it home and looked inside to find a small stick stuck on the impeller

Hes out on it today and just told me 8650rpm /82mph on full tank. Temps in the mid 70s with slight wind. Still seems like the mph is off compared to what riva is claiming. Apparently the other day...

Leave the factory waterbox with through hull and its not loud. Add the riva waterbox and then it gets LOUD

Will do. He took them all off yesterday and re assembled. Cant test yet as its cold and stormy in the South so I will report back once we see.

What was the outcome? Friends 18 GP seeing 82mph/8150 rpm with the following:

Riva intake grate
2020 GP ride plate
Solas 13/18
Fizzle
Riva power filter
Riva through hull
ribbon delete
Riva...

Similar situation last year. ECU was told to be deans, sent it to him got charged $75 for him to say not mine and then paid shipping back. Ended up going maptuner x rather than trying to figure out...

Ill take it. PM me your paypal
