Has anybody installed four blade props on their outboards yet? I'm interested in putting a pair on my Opti 200's pushing the 275 Conquest.

Merc Offshore are designed for just what you are talking about. I have used Merc Revolution 4's on my Bertram and love them (however, they were custom built for the boat by Mercury Racing).

Lou or Roberto,
Do the props actually get the boat on plane faster? Did you notice any real decrease in top speed?

My 22 doesnít need much coaxing to get on plane so if there is a difference in 'time to plane' itís negligible, top speed is probably a bit lower but itís also not enough for me to worry about it. IMO the prop shines through the mid-range, especially in large rollers.

Sorry for my english,
not there are problems for the top speed, the decrese there is but not a lot.

I think the four blade prop would suit your needs alot better then your current one blade prop.

Yeah, I can't figure out why the motor runs at 7500 rpm and I'm not moving too fast. I might be better of with an egg beater from the Turning Point. Do you have a gas powered one?

I noticed that the 225 Merc 4 strokes come factory equipped with the Revolution 4 four blade props. I saw a pair on the back of a 2003 275 Conquest at the dealer. Do the 4 strokes have a hard time pushing these heavy Conquests?

From Mercury's prop catalog, I see that the Revolution prop is designed & recommended for Stern Drives only.
The four bladed "Offshore" is the one you want. Mercury indicates it "provides tremendous lift & agressive holding for big twin engine boats". The Conquest would fit this category. The 3 bladed Mirage Plus Prop is for big boats, with high HP, that have a better HP to weight ratio, like an Outrage. Mercury says it runs a little higher top end than the 4-blade. For lightweight hulls, like the Classic Outrages,
This prop discussion could apply to any brand engine, as the props can be fitted to all brands with the interchangeable hub insert.

I just checked the website on the Revolution 4 prop. It is in fact recommended for v-6 outboards including optimax motors. It also says the mirage plus for top speed on the opti's too.
