New Engine

[JBASS02]

Does anyone have specific prop recommendations for the Etec 90? I've seen 13-¾" x 15" props recommended on other threads? Brands? It sounds like people like 4B for the lift. I know props can take some trials to find the perfect one any help to get there faster would be appreciated.

The motor is on! I need to get a prop. The new 90s have the larger V6 lower unite and take 15" props. I've see people reference using 13x15. Would a 15x15 still work or will the larger diameter be too much with 15 pitch? Any advise or prop recommendation would be greatly appreciated. I'm hoping to go to a prop shop in the morning.

I could barely turn a 4B SS 15x15 PowerTec ELE4 to about 5400 with my 150 on the Seafari! Same with the 14.5 x 15 BRP Cyclone, so the 90 will never spin it fast enough! Ask Terry England what he runs on his 19!

That new motor sure looks good!! Good luck on the Seabass this season.

Thanks for the reply's. I'll post some numbers as I get this dialed in... and some seabass pics...

I took the boat out for a few minutes today. I just ran out a mile or so and ran back. The boat had 47 gals of fuel and minimal/no gear, just me. I used an aluminum 15.25" x 15 three blade prop (only prop I had access to that fits). I planned at 12-13 mph and cruised in the mid 20's with a fuel burn of 5.5mpg. Topped out a 35 mph at 5250 rpm. Like I said this was just a run out and back didn't mess around with anything just wanted to get the boat wet. The cavitation plate is exactly 1.5" above the hull line. I'll post more as I refine.

Thanks everyone for the help. I am amazed at how smooth the boat runs. couldn't be happier.

Holy cow those numbers look good!!!! It also looks great.

JBASS02, it would be nice to see how things are going with the new power. Have you gotten prop & everything dialed in? Looks like you made a great choice.

I've done close to a thousand miles on the engine already. The islands which we spearfish are 26 miles offshore so a typical day is around 80-100 miles. The engine is great! It gets ~4.5 mpg for the average day could be better but I typically run 48-5000 in the morning. At ~4000rpm(~23mph) it's getting 5mpg at ~5200 it get 4mpg(~35mph). Yesterday was our first day of big seas and the boat did great. We left the harbor at 5:20am to glassy seas and got to around the 20 mile mark before we decided to abort and dive coastal, we couldn't see over the waves which where beginning to break... I'm planning to redoing the deck and possibly building a half height cuddy this winter so I'll wait till then to dial in the prop and go stainless.

The 90 E-tecs do fine. Lot’s of mid range torque with a very flat power curve. I don’t post much on the performance because I sound like another “Lying Fisherman”. I’ve worked mine like a dog since ‘06 on my “freighter”. I did have an EMM go out years ago, but that was covered under warranty. Other than that “touch the key and go”.
