Engines and Drive Train / Wet exhaust configuration
« on: February 07, 2022, 11:24:49 pm »
Hi all,  i have looked through the forum but cant find the answer to my issue so here goes....

i finished my refit of Moonstar (98) and ran the motor up only to have the engine flooded (fresh water luckily) - reason was not clear at this stage

it then happened again after launch - suspected reason - draw back of water from the exhaust pipes with the water muffler

then again after i attached my inlet cooling pipe and did not start the motor (therefore no water in the exhaust) and the engine filled with water.  The water therefore came from the raw water cooling side, through the heat exchange, into the exhaust filling it up and then proceeded into the engine cylinders through the valves.  when i inspected the impeller some of the fins were broken and i can only conclude that the water made its way through the impeller and into the exhaust system

So how is the wet exhaust supposed to be configured in the CSY44's?

a very good article outlines the principal that the water injection should be on the downward slope of the exhaust and therefore the exhaust is hot up to this point.  In the CSY44 this means that there wold be a hot exhaust to the top of the bulkhead with the rear head where after this point the exhaust runs downhill to the outlet.

to complicate the matter my Volvo Penta TMD22 injects the cooling water just past the turbo into the exhaust which is about 40cm below the WL.

So the questions are:
 is what configuration do other boats have that works
does the water pump impeller prevent water coming in

Hi all,  i have a CSY44 WO and am now nearing the end of a full year of rebuild. 

I am on the rigging and sails and need a new RFG.

does anyone have the dimensions for a RFG?  i am being lazy but i also want a check against the measurements i will take today.

launching on 25 November and then will tackle the running rigging.
