    Ordered a Solas 15.8 x 15 aluminum part #1511-158-15 Hopefully this will do the job.

    This prop looks interesting. What's your take in this. 16x16. Should add 150, 200rpm.

    The prop I have on is the 15.75 x 17 and it's not in the best of shape. Bent, chunks missing, and welded on. I actually used a rock and picnic bench to straight it sum. Found a next to new old stock prop in the good old USA. Should be here 2nd week of Sept. Lesser Slave lake Alberta Canada.

    Next door neighbor is an ag equipment mechanic. He did the tune-up and I helped, should be good.

    Hooked up a digital tac this morning. Boat tac was out by 500rpm. A new 15.75 x 17 prop is bang on 3900rpm at WOT. The 15.75 x 19 should come in at 3500 to 3700rpm. Considering the manual said 3900 to 4300rpm what do you think about using the 19 pitch prop and running a few rpm lower for...

    New to me 1976 starcraft 25 mk IV with 165 merc. Looks good, runs good for a 46 year old boat.

    That is the 12 foot I was talking about lol.

    Tach was accurate when tuning. At least up to 1500 rpm. I will hook it up and check it at a higher rpm.

    Until you hit a 3 foot chop head on LOL. Then it's sideways to the nearest shoreline and crawl back to camp. Took on my fair share of water that day.

    Old prop is an old merc 15.75 x 19. Got a beat up 15.75 x 17 on now. Will try when the wind dies down. Was told at a boat shop that it should net me a 400 to 500 rpm gain. That will bring me up to 3500 rpm. Motor is rated for 3900 to 4300 rpm WOT. May be looking for another test prop soon.

    Big change from my 12 footer. Let's call it my retirement gift to me.
