Installing New Engine In 95 Speedster - Any Tips?

[egoods]

So I just sent one of my engines off to Seadoo Engine Shop to be rebuilt (I went with the premium engine build, I think it will be $800 well spent, props to Tom for great customer service!).

Anyway, what do I need to know when reinstalling the engine and is there anything I should do while the engine is out? Here's what I'm doing so far.
Rebuilding the carbs (I'm going to do the carbs on the other engine as well)
Replacing all the fuel/oil lines and filters
Rebuilding the starter


Few questions I have:
The two small hoses that go from the oil pump into the ports were both broken, is this likely the reason the engine blew?
Will I need to retime the engine/rotary valve placement on the new engine? What tools do I need?
I have the drive shaft alignment tool so I think I'm good there.

Any input/suggestions are greatly appreciated!

If the oil hoses were split... then yes... lack of oil is the reason. SO... make sure to replace the oil lines on the engine that's still running.


Yes... you have to time the RV on the engine once it comes back. All you need is a protractor. There's a paper one posted, and there's A BUNCH of threads on how to do it.


Other than that... it's a straight forward kind of job... just not the easiest thing in a boat. (lots of working while hanging upside down)

Great info as always. Timing the RV seems pretty simple, I'm confident I can handle that.

The tiny oil hoses weren't just split, they were complete broken off. I have no idea how the engines ran as long as they did with them like that. I'll be checking the other engine when I do the carbs on it. I'm also replacing all of the rubber lines in the boat, I've got the room right now I might as well use it!

Prime the oil pump while it's out of the boat. Much easier that way.

I personally would recommend having the carbs professionally rebuilt. I recently swapped the engines in my 96 speedster, which included such tasks a swapping the rotary valve covers (donor boat was single engine setup) and changing the exhaust manifolds (stripped bolt holes). I feel very comfortable doing such things, but I had a bad experience rebuilding carbs myself on my 96 GTX. It ran lean after my rebuild and burned up a piston. A lean running engine is not getting proper lubrication!

My personal rule from now on is leave carb rebuilding to the pros, but everything else I do myself. To me it is not worth saving the maybe couple hundred dollars rebuilding the carbs and risk burning up a freshly rebuilt engine. Just my two cents, based on persal experience!

Anybody on the forums do rebuilds? I was considering that anyway because I don't know if I'll have the time to do the rebuilds. I'll call around and see if I can find someone locally as well.
