Re: 1997 volvo penta prop

Hrf1, we will try to help you as much as we can, but there is certain information that is needed in order to help you. The following form has all of the information that is needed to help you with your problems finding the right prop. If you do not know all of the information that is asked for on the form please give us the most information you have available as I have a program I designed to find the right prop for any planning hull boat that needs this information, and anyone else who is trying to help you will need the same information. It requires time to find all this information when we have to look for it and in my defense I expect you to be willing to expend as much effort in finding the right prop as I do. We hope to be able to help you get the exact prop you need for your particular uses, and this information is required to do that.
It is not as simple to pick the right prop as most people coming to this forum think it is, that is why we ask so many questions, it is for your benefit we ask all these questions. And if you have a stainless steel prop or are changing to one the blade geometry of the prop can make a lot of difference in speed and RPM.

Iboats Boat and Motor Info

1. Year, make and model of boat
2. Length, width and base weight of boat, look for boat decal on back of boat
3. Number of people and gallons of gas normally on boat
4. What do you use the boat for
5. Is it a Deep Vee and if so how many degrees of deadrise
6. Year, make and model of motor
7. HP and gear ratio of motor
8. Manufacturer?s recommended WOT range
9. Antiventilation Plate height above keel of boat if it is an outboard in inches
10. Make, model, diameter, pitch and whether SS or aluminum prop
11. WOT RPM and speed from each prop

Props are sized by Inches of Pitch,... Not what boat it's on...

Re: 1997 volvo penta prop

Thanks for info..1997 Seaswirl Striper 2150. It has a 4.3 engine and volvo penta sx sterndrive. I am being asked all kinds of info. The prop on the boat seems wrong. Boat doesn't go over 3800rpm.
RUNS LIKE HELL!!!

Any help to get the right prop appreciated.Below is what I am being asked. I don't have the stats for the boat.



Being asked:

- Gear ratio of your drive

- Recommended WOT RPM range

- The propeller in use now, pitch, material, brand, model number/part number

- Top speed and RPM you see with the prop now

- Your subjective impressions of how the boat performs now and what you would like to improve.

With that information we can offer some good suggest
