1981 Aquasport 170 rebuild in Sweden

[RickK]

Yup, very purdy 
I see the scuppers are just above the trough height - nice planning.  Over here birds like to sit on the motor cowlings and decorate them - you need a cover for that new motor cowling.

[larsli68]

They do here too... Yes, I will get a cover for it. I will also get a cover for the center console. I can't wait to take the boat out again. I will shoot some video and post YouTube link.

We took the boat out for a spin tonight. Very windy today, and we only did some time on the engine.
I also started to install the new fuel sender that I received today. This one works with the Mercury smart craft system. The Euro style
fuel sender didn't. I brought tools to the harbor, but not a short ph2 screw driver... I will finalize the install tomorrow night.

Had a fun day on the Baltic with our good friends from NC today. I was glad I had 115hp to move the boat going back. We out ran the rain.
The forecast said no rain and no wind... I'm glad I'm used to these waters since I was a kid. The  weather acted strange, and we left the cottage early.
I'm glad we did. Strong winds and lurking rain, but we managed to get home before the rain.

By the way, finally a picture of me driving the boat. Thanks to Cliff who took the picture.

We finally got a half a day of decent weather here today.
It has been bad for almost 5 days.
The Merc now has 10+ hours on it and is finally broke in.
Feels good. Tomorrow the forecast is really bad weather, but if they are wrong, we will go out again.

Have you tried a different prop yet? Maybe a prop house will let you try out a couple to dial it in before you buy?

[larsli68]

Hello Rick,

The place where I bought the prop, will let me trade until I'm happy.
I'm getting 5100 rpm and 33 knots right now.
I just finished the engine break in period yesterday. The weather is really on and off here. I might go back out today, but don't know yet.
It all depends what the weather is doing.

Hello guys,

Today I worked on the engine trim, and got 35 knots on the speedometer.
Went for a nice boat trip, with stop at the cottage for an hour nap... 
I got so excited that I never checked the revs when I did 35 knots... I will test again.

[RickK]

How'd you do compared to the whaler? Did you have to buy the beer?
Hope not 
35 knots is 40 mph - with a new 115 I would think that you'd get close to 50mph (43knots).

[larsli68]

The Whaler is doing 34.7 knots, but that was with three people in it.
I will try again, do you think the break in period has something to do with it? That the computer limits the engine?

I will take her out again today and try again.

Hi Lars,
What is the rated full throttle RPM that is stated for your engine and what pitch propeller are you running? I have a feeling you are over propped if your only turning 5100 rpm.

[larsli68]

It's 5700 rpm's. I agree, I think I need to have a prop with less pitch. I tried to read my prop pitch today, but I didn't bring my glasses...
Do I need to say more. I used to have perfect vision, but since about a year ago, I need reading glasses.
My nephew will come with me tomorrow, I will ask him to read the prop, and I will post the size and pitch here.

Thanks for your support!

I started needing reading glasses when I hit mid forties.  Been downhill ever since 

[fitz73222]

Yep about 46 for me for the bifocals. Anyway, check the pitch, I'm thinking you have a 21 pitch on there now and a 19 should get you where you need to be, maybe even a 17 it depends on your gear ratio. Then say by by to your brothers 17 Whaler, which looks to be in very nice shape, he keeps up on his mahogany and teak! Also do your prop testing with your normal load of passengers and fuel.

[larsli68]

Thanks for your prop input. Very helpful. I will check this weekend what my pitch is, I forgot when we docked yesterday. I have no experience with this stuff, but I can clearly feel the boat not accelerating the way it should.
With the old 120hp Evinrude, it jumped out of the water.
Posting a couple of pictures from our trip yesterday.
