2 more tips - - Avoid anything that puts the impeller out of the water - getting airborne between waves, etc - this causes the supercharger to rev out of control and can cause it to overboost he engine or break the supercharger - The best way to get around trailers and docks IMHO is to leave...

Extremely clever. I'm a little worried that well nuts will not hold in a 50 mph blast..I hope it works. I might try something along the same lines but mount a larger windshield to the silver part of the lid, more forward. That way I could drill all the way through. . However that has drawbacks...

Fatal Flaw You are experiencing the fatal flaw in all Sea Doo boats. Yamaha boats have removable plugs just above the impellers so you can remove sticks, ropes etc. There is no possible alteration or substitute intake grate. On the Speedsters you cant even remove it without going inside the...

Washer Probably a spark plug washer got forgotten and dropped into the cylinder

Hold On I would not install any of the following if going over 50 mph: - Any bimini which has straps, especially straps which are held by screws into the fiberglass - Any cheap bimini If you are going 50+, and a 20 mph wind also hits the bimini, it will rip the screws right out of the...

Why The 255 ? Because a 300 HP is not available ha ha I got a great deal on a 2009 left over it was sort of an impulse purchase. It is fun but a non-blown 180-200 hp engine would be better, like the 4 cylinder Yamaha jets.

Auto Engines Lets see, a stock Corvette 7 litre engine produces say, 500 HP, which is 71 HP per litre. A Sea Doo 255 engine at 1.5 litres produces 170 HP per litre. If the Chevy engine were tweaked to produce the same power, it would be 1190 HP. How long would a 1190 HP Chevy engine...

Top Speed All this talk about top speed is silly. These boats have no windshields, you cant go over 40 for any length of time without getting extremely uncomfortable, especially the passengers. In hot weather it is like being microwaved. And if you hit a solid wake or wave at that speed, you...

Cavitation ? Are you sure there isnt a small object wedged between the impeller blades ? Look with a flashlight from both ends. I once had a 1 inch stick wedged almost out of sight, caused those symptoms

Good One Yes you have to do that to rinse out your muffler bearings NOT After flushing, if you just run the engine 5 seconds the supercharger will blow itself clear.

Trashed I threw away my Yamaha jet boat because there is no Poppy cover for it. Give me Poppy or give me a Sea Doo

Capt Steve Good Advice However it sounds like it is falling on deaf ears. Does anyone remember the 2 football players who drowned off Tampa a year ago because their 23 foot fishing boat CAPSIZED in rough water and they could not hold on to the bottom of the hull which was upside down ? Crazy...

Cheap This is not the best purchase to make. The 2007 and 2008 had the old supercharger washers - there is another thread on here where a owner is facing a $ 5,000 overhaul at only 240 hours or so due to that issue. Very common situation. There are still many 2009 left over Speedsters...

Hold On SeadooSource dot com sells a float replacement which is hard plastic instead of the foam original - highly recommend. Easiest way to get it out is loosen the electrical box, yes its a pain but not terribly risky.

Done 2 Times On Yamaha 21 footer and Speedster 150. It is a great product, prevents much hull damage due to bumping trailer, hitting branches, beaching etc. it will yellow if left in the water full time, after about 5 years. You cannot easily remove it, so apply carefully. Prep is not...

Amazing I wonder how many other 2008 boats are still un-sold. I saw a 2008 Speedster 200 on eBay recently, went for 28 grand which was a tad high. But better than 40K for a new one.

Wd-40 Redux The many uses for WD-40 are mostly because of the Stoddard Solvent contained in the formulation.. and you can buy large cans of Stoddard for about 1/200 the price of WD-40. having said that, Duct Tape and WD-40 solve 90 per cent of mechanical problems and 50 per cent of...

Nix WD-40 Although Dr Honda is papal in his wisdom, I have to caution against his WD-40 advice. WD-40 is just kerosene and Stoddard Solvent, it has no lubrication properties at all. I would put a couple ounces 2-stroke oil into each cylinder, let it seep past the rings (24 hours or so) then...

Avoid babbitt's Since you mentioned Babbitt's Sea Doo parts, their prices are low but hey will burn you on shipping charges and in fact they took my money and delivered nothing since October. Many calls to them, always 'we will check into it' etc etc etc
