There is no water flow to my heater on my maxum when the engine is at idle. Once up to 1200 rpm then the flow is fine.<br /><br />I've checked the raw water pump impellor today and it looks good as new. <br /><br />Any suggestions?

Looking at a friends inboard ski boat with the 5.0 mercruiser model MTE230.<br /><br />The boat had not been used for a few years when he got it so we did compression check - 6 @ 150+, 1 @ 140 and 1 @ 130 but the low ones went up with a little oil.<br /><br />Put on new leads, plugs, cap and arm...

Looking to change to prop on my merc. It has the factory fitted 3 blade prop (not sure what pitch).<br /><br />I would like something lower pitched as when I'm going 20mph its right in the flat spot of the rev range just before the power band starts and as such its hard to keep a constant...
