I have the same set-up, 90 ETEC on a SR 5.4. Great combo.

Running the standard BRP aluminum 13.25 x 17. Dealer set up the boat with the engine raised 1 hole. No cavitation problems. With that set-up and 1 person with little (<5 gal) fuel and no gear aboard, I was getting about 5200-5300 RPM, when trimmed properly. Don't know about speed, but it feels pretty damned fast! Recommended RPM range is 5000-5500. The tech was pretty happy with that set-up when he tested it. I want to switch to a 15P prop, as when I'm running my normal load of 1-2 adults, 2 kids and a bunch of gear, I can't get more than 4700-4800 RPM. I'm pretty sure the 13.25 x 15 is the best overall BRP aluminum prop for this combo unless you're always running really light.

I'm tempted to go to a Michigan Wheel Apollo stainless, but it's pricey... I actually think a 4 blade would be best for my use, might help keep me planing at lower speeds, and give me better towing bite when I'm pulling sailboats.

Do have the dealer check out the tach though, I've heard of a lot of BRP tachs under-reporting RPM...


P.S. my boat does has Nauticus Smart-Tabs, though I don't think that has much bearing on prop selection. Does help get and keep the boat planing though!

Thanks guys, and thanks Dan.

Was hoping you would reply to this one, since you have the same combo

Have been chatting to Micheal in Coleriane (the most local e-tec guy) and he is going to lift it a hole for me sometime during the week, so that's good.

I also have now fitted my brand new standard prop (which I got from sion mills) and hopefully that will be a good job.

My journey to sion mills also made me purchase another toy....... a yamaha jetski (INFLATABLE!!!!). So damn cool, so I reckon I will cruise up the river past my office on that today.

Have now also got my A frame fitted, with lights and aerial and have collected my new 6hp Johnson, so looking good.

Just a few fiddly bits of painting and tidying at the boat now, and Scotland, here I come.

Anymore advice on paint for the hull, where to store the Johnson, good waterproof self adhesive rubber (for sealing up the seat) etc is all mucho appreciated.

Finally if anyone needs A4 stainless fixings, try
