Engine is now running great. Dual bypass for Bob's worked. Temp gauge. needs replaced. Head warm to touch after high speed and high temp per gauge.
Just put the chopper on and raised the jackplate 2.5"

Well, it runs and doesn't overheat with the dual low water bypass hoses. The gas tank turned out to be half-full of water...overflow valve was pointing up...think this was the cause.
Started and water was coming out of the rear block :cry: Block is fine, rear gaskets not even there :!:
I'm hittin' the water on Sunday with my fingers crossed :boating:

Thanks...gauges are a 'bit down the road but I will start looking for. I wouldn't have been able to get this boat if I weren't a concientious spender...sounds better than cheap :0)

Jeff I just bought a used gafrig gps speedohead unit for cheap and in keeping with my cheap ways I didn't want to spend the 200 for their gps reciever so I dug throug my stash and found a garmin 35 reciever will work. I see them on ebay for 50. I have less than 75 into mine so watch for a used head unit or buy a new one but this should save some money for the other gauges.

Ok, I'll make sure it is checked.

I'm "almost" positive it is an undersized bypass hose on the low water pickup. I'm getting both sides done right. Also replacing stats :oops: entire waterpump and anything else that looks even slightly worn or could cause overheating while it's torn apart.

Any and all thoughts or suggestions are greatly appreciated. I've been a boater my entire life, but this is new territory for me. I have a lot to learn...learned today, Livorsi gauges are more than a little expensive!

I'm looking at 10/17 for first run and will have gps along :D
I will keep you posted and thanks for all the help.

Another thing I thought of. If it only overheats while on plane it could be the gasket under the water pump base plate. If this is torn or out of place it will suck air. it only does this while on plane because at slower speeds it's under the water and it doesn't mater if it's sucking.

Just some thoughts. I did mean thermostats it was just too much to type "I'm a little lazy".

Good luck and keep us posted.

Gotcha...thanks. Yes, replaced.

There is no alarm, using temp. gauge.

Will check pop-off valve and water pressure when reassembled.

Torque reducer on skeg was bolted on...way too much drag....having it welded on.
Just ordered a Mercury 24p chopper...this puppy is gonna fly :0) Preparing myself for the "dope slap" I'm sure to get from my wife :0)

Thanks all for your help!

I'm bettin' he meant thermostats.

By the way, what indicators do have that the motor heating up? Alarm, temp. gauge, or other?

Hey, that's a clean looking ride you have over in The Boat Show!
Congratulations and welcome. :up:

Ok, bear with me :0) I understand everthing except stats...are you talking about stator? Ordered. Haven't checked the pop-off valve, unless this is with the cowling on and found wax jammed in what looked like a water indicator on OMC.
I'll check water pressure and report :0)

Thanks for your time,

Jeff
