Hi,
for those with experience running the small 70CES lower (or the 48/55/60hp 2Cyl lower) on either the 70 or the 2Cyl 55/60hp engines, I'm looking for suggestions:

- run with or without a thermostat? (poppet too, on the 2Cyl)
- use a different tell tail pickup location..? (top of the head on a stock 70 to mimic the CES head?)
- epoxy the top half of the plastic water inlet inserts..?
- custom inserts that "scoop" more water..?
- what kind of pressure numbers should one see (with and/or without thermostat)?


I am not running a nose cone, and low pickups are not allowed. I can only use the inlet location above the prop shaft on the sides of the lower (stock location).
I am currently running both the Yamaha 850cc 70hp and 760CC 55hp 2Cyl, they share the same lowers. Both are on padded v-bottom hulls (Delta and a Voodoo).

cheers,
M
