I recall a thread about torque steer where a member switched from a three blade to a merc four or five blade and he (she) reported a significant reduction in steering load. Anyone recall this one? I was going to price out props and wanted to know what merc model he bought.

For the best prices I have found, and great UPS service w/no sales tax, on Merc props, go to offshoreperformance.com. I recently paid $365 for a new Laser II.

The Trophy Plus 4 blade bass boat props are the low steering torque props, but not applicable to a Whaler, and not available in CR. They are a 4 1/4" mid size gearcase prop, but they can be run on a 4 3/4" large gear case engine also, as in a Bass or flats boat.

For a Whaler, you would want either a Laser II, Mirage Plus or 4 blade Offshore prop. Check out mercurymarine.com first, for application descriptions. I use Laser II's, but my boat is light and fast relative to the HP, which is what they are designed for. You might be better off with the Mirage or Offshore.

Thanks Larry,

I saw that on merc's web site, itís what prompted me to post. I didn't see a merc prop listed (using the prop selector) that was a torque reduction model. And yet I recall a member reporting a BIG torque improvement on his whaler with one of the merc 4-5 blade props.

The selector recommends a 21" offshore but not the Laser-II, it spit out the "Mirage Plus" (If I go for a 3-blade I will be the Laser-II base on your glowing reports)

The OR-25 motors came with SS-19"s I thought I would test those out before shopping. The 18 is propless at the moment and I thought torque listing may be a problem with that big 200!... I'm sure I'll find that thread right after I buy the prop.

Pete
