We put the RubyToo in the water for the first time today and everything went fine. She started and off we went at about 70% throttle, after about 10 minutes running we noticed steam coming from the exhaust and the exhaust water was very hot, the motor was very hot to touch but not burning to touch.
We tested the the motor out of the water many times over months prior to launching we had a large water container hooked up to a flushing out hose fitting that bypasses the water inlet and filter and she would never run hotter than shower water.
My questions are , is the extra load from the gearbox and propellor causing the extra heat or is the engines water pump not through the inlet scoop sucking enough water? any help would be great.

She looks really beautiful in the water.
The P55's do run fairly hot when working. I know of 2 in our group here on the lake that both blow steam from the Exhaust and also others I have seen at various outings do the same. You should not be able to hold your hand on the head as they should run around 88 deg centigrade, which is twice as hot as a shower.
Typical British engineering have finer tolerences than the old Blaxlands, Simplex etc and are treated more like an Automotive Engine.
Just run it and keep an ear on how it sounds but all should be well.
I told Ron I would get down to have a look at the timing etc but have been flat out trying to get my new boat finished by this weekend. Still have to fit the P55 and make an exhausr system and the heap of other things that crop up.

Dave, thanks very much for your advice, we had a great day out on the water on her first sea trials.
We will be having a official launching in the near future.
The speed we got up to surprised my dad and myself,
we feel very confident with the Stuart.
The RUBYTOO was made for my family, especially my youngest daughter Ruby [four years old] who has Rett Syndrome, http://www.rettsyndrome.org/ she just loves the wind in her face and i am sure she will be smiles from ear to ear in the RUBYTOO.
Thanks again , Matt and Ron.
