Thanks. I suppose my question is if i do no upgrades to the engine would i have diminishing returns for the pump

I assume that at some point a larger pump like a 155mm with lets say a stock 701 would do nothing aside from cause a lot of loss on the bottom end due to a larger prop being spun and more water being pushed. Is their a rule or thumb/gold standard to engine size and modification? Im trying to...

Ya i suppose ill look the cost for everything as of now and factor it all in. What are some other hulls like xfs and the v3 that might be around the same avenue of what i want to do if i decide to go used?

I seriously appreciate all the help and suggestions. Building the ski will be challanging, but im okay with the challange regardless of time, havint had a ski for a while so its not like im missing ride time anymore than i already am. Also i dont want to nickle and dim myself to death and i...

Is this available still?

Give the motor a little love like rebuild or add more hps

Im trying my best to do a search and cant seem to really find a HOW too thread and im sure its because where everyone get their power centers are different. Basically dad has a mint condition 1994 wave raider sit down with a stock dual carb 701. im a diesel boat mechanic and i repower old...

cool thanks guys. i think i might just consider doing a 750 engine. this would be my first time building a ski from scratch. thanks for the advice

Has anyone ever thrown a 800 kawi or yamaha motor in a 550 hull? Thinking about building a 550 like this ( http://www.x-h2o.com/index.php?threads/550sx-hull-modernization-build.110961/ ) and throwing an 800 in it. if its not realistic then im not gonna bother.

Did some further investigation. Seized the crank. Top end is screwed. Everything basically done. Dont know what happened all i know is that it looks really bad. Question, Buy a used engine from someone or try to fix it all.

okay. well im gonna start putting money away now that way i can get some work done to the ski and put it in the shop in about a month.

interesting, do they sell heat sensor set-ups for skis, almost like engine temp for cars? think that would be pretty cool to have a heat temp gauge on the handlebars and give me a little assurance that nothing is falling apart while im riding the thing.

just a thought, kinda been thinking about this all winter, with all this new found heat from the port and polish, since im running none girtled, is it possible im loosing compression after awhile due to a warping effect to the cylinders/head heating up and cooling, and not having the head bolted...

10-4 CMDR

well my last ride went as expected. did fine for a day, topend felt like i was ringing its neck so i stayed off the top end, then i took it for a short ride up the river and it cut out completely, tried to start it up and when i hit the ignition switch, it wants to turn over but its almost like...

Leak down test?

So i got everything back together. Everything is torqued now with new gaskets so hopefully it does well this weekend. Ill let you guys know how it goes.

Guys i need to know if im looking for foot pounds of torque. What kinf og wrench do you guys use because im trying to get one that wont be a pain to turn in the hull also

That would suprise me to see if any were actually in stock. Call them, their answer will probably change. Not 100 percent positive on the FX1 chamber and the MOD chamber. Im assuming the FX1 would be easier to tune because the design was made to fit the fx1, and possibly less of a pain the the...

And i also agree. But for me thats THE VERY last thing i want to do especially since putting together the engine myself saved me tons of cash that i didnt/dont have. But i also think that if i put it together correctly this time it will be absolutely perfect. All the fine tuning is done. Art at...
