Re: 1987 Bayliner Trophy Hartop 4 Blade PROPS.. I dont know what buy

Don't get a prop until you get us your performance numbers.
Your diameter seems undersized at 13 1/4" X 17. 17" props for 3.0 are 14 4/5 diameter to about 15"
Does your present prop seem to have issues?

The OMC 400 stern drive is a 4-1/4" gear housing. Like the same size as a V-4 gear case. Any 4 blade prop available for it would be in the 13" diameter size range.

I'm a little confuse.

So 13" x 16p is what i should purchase?

Where did you see a 16 pitch available?

All I see is 2 inch increments up to 19 pitch, then one inch increments after that.

So it seems that your choices are 17, 15, 13, etc.

You needn't purchase anything until after the water test.

Well the boat was Almost perfect.

The good:

1.The shifting from Reverse to Forward "vice versa" was good.
2.The idle was great. No hard Shifting.
3.The engine runs without any issue.
4.The Temperature is great.
5.The Hull is good. NO leaks. very stable
7.All the pump works

The bad:

1. BOAT slow as HELL with ONLY 2 People.. I will most likely have 3 kids. 3 adult
* 20Gallons of Fuel
* No water inside the hull
* The Engine seem like its RED LINING, but it seems like its going at 15MPH
2.Maybe the RPM was incorrect. but when push to the petal. the engine sounds really loud. but the boat was going maybe 15MPG
3.Trip tab has a LINK on 1 hose.

-------
I'm sorry guys. my GPS on my phone for some weird reason it didn't work . I'm not sure how i'm going to help you guys with the information you'll need to help me

But I know this for a fact> it seems like its red lining "RPM" while ONLY going about 15MPH. SLOW *** HELL for me.
but then again. its only 140HP..

Please advice. i never had this issue

I'm not sure if the gauge is accurate. but i was going by the SOUND. it was HMMM HMMM HMMM HNMM. loud.

3000+. but the Gauge it self could go up to 6000. but it never reach half way.

what Bondo said.....what did your TAC read at full? is trimmed down all the way? assuming your engine power is ok, 140hp with best prop application should be able to shove that boat up on plane and get 30 out of it, I would think...........
