From your "steering" post we all thought you had an outboard ...

What prop do you have on there now ?
You might have to remove prop to find pitch number, could be inside hub.

What RPM's are you getting with that prop ?
You want to keep it in the max rpm range of motor.

What speed are you getting now, with current prop ?
Is your prop in good shape ?

Diameter is not as crucial, the pitch of course is.  The Volvo props for that drive are very good if you can find one.

I am going to try to attach a Volvo Prop Guide.  If not successful I may want a moderator/admin to help.

Also,  you can download a Manual from this site...:

http://www.volvopenta.com/VOLVOPENTA/NA/EN-US/MARINE_LEISURE_ENGINES/OUT_OF_PRODUCTION_ENGINES/Pages/out_of_production_engines.aspx

Type in aq130 in the Product Designation.

In the Owner's manual there is a section that describes how to adjust for any deviation in course.

Yeah,  very nice, glad that worked.  Had problems on "other" sites with that one sometimes.

    had a 14  l   19  on it....yesterday we switched to 14  r  19.....got the steering to work good....with only me in the boat I get 4800 t0 5000 rpm....if I put 4 people in the boat it has a hard time planning....I am thinking about a 13 pitch prop...what do you think????  thanks...


Gregg's reply ...

Some times one prop won't work for every situation, or you can find one that work OK, but not great for most situations.
Best bet is to try as many props as you can find, all on the same day / time.
A new prop might work better then one that has been re-worked, or re-worked prop might work better, no way of knowing until you try them.
You'll be the best judge of what works best for your needs, with the motor is in it's rated RPM range.

I have a Laser II 22 P prop on my motor, but keep a 19 P aluminum prop in the boat as a spare.
If I had 4 people in the boat and wanted to pull a skier, I would change to the 19 P prop.

That engine has a 4600-5100 top rpm range, so the 19p is pretty close.  I would not jump from a 19p to a 13p though.  I think a 17p would probably do what you want.  Maybe use a 15p for watersports when you will have lots of passengers.
