I have done a search on towing your craft to see if there are certain hoses to clamp etc. Wasnt able to find anything. The manual doesnt say to do anything but to tow at 5 mph or less. Any ideas? Thanks.

Are you kidding? We don need no stinkin towin!!!

5mph or less?

That way it would take me 1 day to reach the water. I just drive with the same speed as if I weren´t towing.

He means towing the craft on the water.

on some of the sea-poo's you have to pinch off the water line coming from the pump otherwise the engine will flood with water while towing.
That's on a sea-poo...most of us here ride Yamahas.

erm...ops....stupid me...sorry.

I´ve seen people towing their jets at way more than 25mph.

serious
...alrignt now...toke and pass

Thanks for the humor. This is the second time today I have been laughing pretty hard after reading some posts on this site. The other was about how to keep someone from stealling your GPR. So on a serious note I am assuming that there is nothing that needs to be done and it is a Seadoo thing. Of course I did buy a Yamaha so I wouldnt have to be towed off of the water! Thanks to All.

Ah, the No GPR Security Post, I especially liked the glock comment!

I think the towing speeds are a problem for all PWC regardless of make. The water will flow through the pump and pressurize the cooling line and force some water up into the engine. With the motor off it can back up the exhasut into the engine.

I'm pretty sure it is an issue with Yamahas and all other PWC, how significant a problem it is I'm not sure.

Its very much an issue with Yamahas. When they say 5 mph or less, they mean it. As stated, water will flow into the cooling passages and subsequently into the exhaust and into the motor. Not a pretty sight.

the water for the cooling flow into the engine through that little hose that is inside the nozzle and then exits it and goes into the hull right?
But how come that that little piece of hose that is in the nozzle is turned to the outside, against the pump, how´s there enough pressure to the water to go through the hose?

I'm not sea-poo bashing here... but in 7 years of riding sea-poos are the only skis that I have had to tow in.
That little brass tube your looking at is for the bilge pump vacuum.
The cooling water comes from that little square box on the side of the pump/stator housing.

Take note on this though...and Todd can vouch for this one...if you ever have to be towed in from the surf...the 5mph rule goes right out the window. When being towed in from the surf, its all or nothing or you will get bashed by breaking waves...then ya got two ski's that need towed in.

Ed - not bashing but you call it a sea-poo? sounds like bashing to me. As for my SEA-DOO, yes its been towed. It has also towed every other brand out there too except for tigersharks - there aren't many sharks in Okinawa. I'm sure the day will come when my SEA-DOO has to tow my GPR too. Don't care what brand it is - run it hard/long enough, and it will break...

Sorry about that - got called away to dinner and didn't get a chance to post what I started too...

In my experience (and opinion), you don't need to clamp the hoses if you are going to tow at the relatively slow speeds we tow broke skis behind another ski. Although some pump pressure builds while towing, the impellar is not spinning so its insignificant. In fact, the non-spinning impeller may even hinder the build up in pressured to pump water thru the system. Some may challenge my "non-spinning" impeller statement. Thats ok. I just don't believe that the water pressure created by slow towing a ski would be enough to overcome the engine compression and spin the prop.

If a ski is going to be towed behind a boat at high speeds (like when traveling to outer islands etc), then I agree - the ski (doesn't matter which brand) should be clamped because higher speeds may spin the prop enough create enough pressure to push water thru the cooling system.

I have towed and been towed lots in my relatively young 8 years in this sport. Haven't had the water creep up into the motor yet...

Hi guys!
Seemed like a good one to jump in on. Spoke with a tech at my dealer and he told me it would take speeds of about 40+ to force water into the engine??? And trust me, he'd be the first one to b**ch me out if I tried doing something stupid with one of my skis. But I'm with the rest of you, bought a Yamaha so I don't have to worry about being towed!

BTW....Hi Ray~~ Hope things are going well for you over in Japan! Tell Momo and all hello!

40 mph+, I filled mine last year doing less than 5 mph

Cant pinch off a line, Then stuff a shirt in the pump if the grate is open enough.

Here one for ya: we were towing 4 skies in tandum at night my sea POO was the last one with a light on it so we could see it.

well were towing for a wile and Hmm were is the sea poo . the thing was upside down filled with water.

That XPL was the worst to bew towed and it got towed a lot

GPR O tows, in pulled in my shere of sea poos tho
