• Exhaust gas temperature (EGT) based fuel compenstaions (optional) Thats key! Based on the facts, this could be a good system. Personally I wouldnt build one purely based on the time it takes to build a map on the dyno. Without one, youd be looking at 100+ plus hours writing a map

We will have to get a beer sometime and go through the theory.

So if this beacon can read 100m through snow, why wouldnt it go 5m through water?

According to my handbook here, post avalanche snow is 80percent water density. How much of that is ice vs water? Just curious. Id like to atleast test this.. Got a snowmobile 260 ft down in the lake right now. Now that is what you call gone forever

Avalanche snow is vastly different than regular snowpack. Acts like water when its moving, concrete whens it stops. Im not saying its close to the density of water but its a lot closer than average snowpack. Ive been accurate to a foot diameter 15 feet down. 6 guys, 8 hours digging. A beacon...

Youre just adapting the 1160 cylinder?

That will put you close to 195 on the guage.

Call Hedlund for ANY polaris crank - 218-463-2911 Hes the man

Retorque the cylinder studs every ride for atleast the first twenty hours. These cylinders are a very poor casting. Ive had atleast ten that seep coolant out the side.

Use thread sealant on the head bolts. Dont use the studs CS supplies.

We had aluminum slipon bottoms for 550s back in the day. They handled a little goofy until we sandblasted them. Also they dont glide on rocks like fiberglass, they just stop. Need some uhmw replaceable bottoms for serious whitewater. Anybody want to make me one?

I used a Skidoo motor mount on mine, mostly because I had plenty. Bolted right up to mine. Sd #512060387, theyre probably expensive from Skidoo. Might try Pam, she didnt know there was a different style than a lord mount used when I tried

I didnt realize Landslide has gotten so tame, time to hit it on the skis

A little fun we were having on the lake this year, thought some of you guys would enjoy this. The last video is a little rockcrawling we had to do on the snowmobiles to get back to the snow. These were all the same day, we also had a quick moto ride in the afternoon and ended up surfing to...

Yeah I need to address that, havent quite decided if Im going to move the pump or clearance the shoe. rideplate had silicone on it but I peeled it back off. Love the hull! It has the best characteristics of the old and new bottom decks. Its a little long but if I decide to keep it, Ill slap a...

Im having a slight cavitation just off idle that Im having troubles diagnosing. Its not terrible, itll pull through it just fine and still has plenty of "pop". Just enough to be irritating. replaced pump seal, no difference. Midshaft seals are new. Midshaft housing looks ok. It had the old...

On my SN waterbox where the elbows are glued to the box, the glue is cracked. What have you guys used to reglue these?

1000LD Cat would be perfect. 160-170 hp at 7000-7200 rpm. And thats stock. Even with a inefficient watercraft exhaust, it would rock.

I wouldnt even consider it unless youre running a lot of rocks like our crew. But for rocks, yeah its great except that when you hit rocks with glass, you continue to glide over. Aluminum digs in and you got from 15-20 mph to stop pretty fast

Let me see if I can round up the old 550 aluminum hull. Its here somewhere...
