Water Pump question

[daveb]

Just a quick question for the experts. I plan to raise my radiator about 12" and wonder if there will be an issue with the water pump not having enough power to cope with this? Its the standard Rotax split radiator on a 582. This is currently bolted on to the gearbox and head bracket.

Thank-you

My radiator is under my engine and has over a 5 foot of hose to make it to and from the radiator back to the engine. No problems.

Raising the radiator above the engine I don't believe will be any problems either. That Rotax water pump is pretty strong.

In a closed system, the water pump is not pumping to a "head" but rather just circulating the water. the height above the water shouldn't make any difference.
