Stern lifting prop for 20 MA with bracket

[McGillicuddy]

Not really a prop guru but...

A "little heavy in the rear" is probably an understatement! These boats were designed for ~300 lb motors hanging on the transom, so when you put a 400+ lb motor on them and then move it 30" aft, it's no surprise that they don't perform as designed! Don't know what your motor weighs, but it's probably similar to my E-Tec which is about 427.

In fact depending on the model it's 475 to 539lbs. Sir, dare I say it, your seacraft is seriously suffering from stern squat Check the model of your current ptprop. By dimensions and appearance I'd guess its a PTC3 or RAS3, or an SFS3 ("Baby OFS"). I may be way off, but it should say on the prop. Check it to get an idea of what the prop is designed to do.

The PTC and RAS are a bow-lifters like the Rapture or Stiletto. Definitely not what you want. The SFS is similar to the Yamaha Saltwater series and would probably be fine if not for the extra 175 lbs set 30" off the stern like a bully on the teeter-totter. That in a four blade might help you.

Even better, you might consider an MQS3 which is a stainless stern-lifter in the mold of Mercury's Black Max. I have seen them on a website for a little over $300, plus the hub. It's a 14.00" wheel in 19 pitch and 14.50" in 17", and it is considered easy to turn. The the extra blade surface area should help to lift that heavy stern load. I am not sure if they make a 4 blade MQS for your motor but its certainly worth ascertaining. but I think the MQS is less costly and would better serve you. Also their SCE3 and SCE4 are stern-lifting semi-cleavers that mimic Yamaha's own semi-cleavers. Probably also decent choices. Good Luck
