Yes Phester it would. But with the armstrong bracket it is set 1" high for every foot back off the transom the bracket runs. I n my case it sits 30" back so it is supposed to be about 2.5" higher. Mine is approx 4-4.5" high. With the heavier engine that 2.5" would likely be a moot point because the stern would sit lower, but with a 1999 115 4cyl and the positive flotation that bracket gives those 2.5" are causing problems

Willy,
I would question just how much the situation you describe*will improve with a heavier engine. *The stern might sit 2" lower with the 150 when the boat is "at rest" .... *but that is not the critical time for you. *You need the engine 2" lower *... *when the boat is "up on plane". *When on plane, the height of the cavitation plate - relative to the keel and to the water level flowing by - *might not be all that different for the 115 vs 150. *At least ... *that is how I see it. *I am interested in knowing how you make out - *good luck.

so at the end of the day, you're still 2.5 " too high while under way...like Brian said

Gotcha guys, I understand, right now I have one more hole left on the engine I can go down, I can also drill new mount holes in the braket. It looks like I would have at least 1.5"s there I can go down. And though I would like to go with a 150 I can't afford to do that. But I do disagree that that would not effect the problem. I think even on plane the boat would sit slightly lower in attitude toward the stern and that would make a difference. I am also installing a 9.9 kicker motor on the stern this winter that might even help a little. So that motor and lowering the engine approx two inches should solve all ills.

Willy, those brackets are ENGINNERED to specific configurations...you might wanna talk w/ Armstrong prior to redrilling mounting holes...my HOPE is you can, but I'd sure check first...there are props designed to run close to the surface that might help you out, but if you can't get it down enough otherwise, I'm like MJ...might have to relocate bracket :'(...

There is a ''formula'' that says for evey X the foot is away from the transom, it needs to be X above the keel...Armstrong should give it to you...you might wanna call 'em... ;)...

OK...dummy here just realized page TWO!!... ::)...sounds like you're on the right track...

Had me goin a minute there Rap, good recovery ;D

[Seacrets]

I don't know if Armstrong has this available, but some manufacturers have local installers that might be able to help after they examine your installation. Maybe even a factory rep in your area.

[willy]

Thanks Seacrets, don't think I will need them, spoke with their tech on phone and he agreed with my take and approach to correct it

[reelapeelin]

Willy, really glad for you that you'll be able to redrill instead of repositioning the bracket... ;D...

[willy]

Me too Rap ;)
