Hey everyone. My 1998 SPX is still getting water inside. I replaced the carbon seal, the old one was really bad, and it still gets water in it. I’m not too sure where else water could come in. Water looks like it was slung everywhere in there so I’m really thinking that the carbon seal is still...

Hey there, I’m building new engines for my challenger 1800 787 and I just put one bottom end together last night, it went together ok but the crank has some resistance to spin over offer lightly torquing the case together is there anything specific that can cause this? Thanks guys

Good day, I have a 1996 XP with a 787 engine. It starts fine on the hose and will rev up easily but as soon as it's in the water it will start harder and won't rev up at all will just sit and idle, as soon as I try to rev it wants to die. When I bought it it was doing it found sleeves where bad...

I have a 1999 Seadoo GTX Rfi I connected the hose to my ski without it running and now I have water in my crank case. Is there a DRAIN plug ? If so, where is it ?

When adding oil to the pto side of the engine, what type of oil do I add? i have a 1997 seadoo XP and I have a case from a 1996 787 engine, So I can’t remove the oil cap. Why do the shop manuals have different oils for the same engine??

Putting my freshly rebuilt 787 back into the hull and was connecting lines, cables etc. Got to the pulse line and went to tighten the hose to the nipple when it came out of the block! I thought it broke but it seems like it was just pressed into the block. You can see from the pic that it is...

Got my 787 rotax installed back into the craft and have begun the reassembly process. I noticed this port diagonal from the center of the rotary valve, does anybody know what it is for? I have searched the owners manual over throughly and can’t find any mention of it, however I doubt any OEM...

Hello, I recently picked up a 1997 XP that needs to be rebuilt really cheap with trailer. So i started tearing into this thing knowing that it needed a top end and really hoping the bottom end would be in good shape. But the previous owner had tore most of it down and saw that it needed a top...

I had my seadoo 3d 787 RFI out last weekend and it filled up with water, engine included. I pulled the plugs and blew out the water. I got it running again but now the oil is pumping in like crazy with white smoke coming out heavy from the exhaust. Am I in to replace the whole oil pump or could...

I have up for sale, Buckshot Head with two different Domes, Carbs with fuel pump, and rotary Valve cover. It is the purple set. If your interested in the set let me know. They are lightly used and have no pitting on the domes. One of the dome sets looks like it was almost never used.
