    For those with a straight pipe setup

    Has anybody had any problems with water going back the exhaust and into the manifolds? I know it could happen when the boat is stationary, thing is has it caused problems to anyone here?

    I havent had mine out, but from the set up it looks like it would be hard for it to go up the exhaust elbow and back in to the manifold.

    The 250 is unlike most watercraft exhaust due to the SC location.

    The header has a vary high over and down in it. This helps prevent the symptom you speak of. Ive left mine in the water with no issue. In fact it helps save the exhaust valves from rusting. The water box holds water even after a blow out. The condensations condenses in the manifold and puddles on the exhaust ports. Straight pipe leaves no water at all in the exhaust during storage.

    You will! I wear a helmet, and its still loud! Even at idle. R-Rated has some for a decent price.

    I just got mine done but to be honest, if i had to do it all over again id just buy the r-rated setup. It was a hastle finding all the silicone hoses for the piping, especially being in a weekend at where a i live. Talking about noise, the first time the engine barked after installing the exhaust scared the **** out of the mechanic lol. It is extremely loud, and it kinda brings the motorcycle roots of the engine into life. I will try it in the water tommorrow, hope all that roar is gonna give me some gains.

    when you run a strait pipe setup ,use the stock elbow on the back of the ski . It will sound better in the water !

    Ultra250 Tn I used the stock primary water box brass nipple and welded it in

    straight pipe near the 90 degree bend.

    R rated thanks for the suggestion as thats what im running at the moment.

    If you look at the head pipe there are to 2 small openings on the outside of the head pipe, they are small square openings where water flows, its a water jacketed exhaust.the last piece of the black part of the exhaust,id post a pic, but they are all loaded on my desk top, I am on my laptop.
