Default Prop Size & Brand for 3700 SCR???

Hi guys, I just bought a 1998 3700 SCR. The boat is in terrific condition, but has a bent prop on the starboard side. I'm getting ready to move the boat from where I bought it to my home lake and would like to replace the props before setting it back in the water. I'm not willing to wait the time to have the prop reworked, so new it is.

Can anyone tell me pitch, diameter of the prop on the 3700? I have looked high and low and can't find the info anywhere.

Also, anyone have suggestions on where to buy parts for this boat? I have a swim platform light and anchor light that need replaced.

I appreciate the suggestions and help!

Welcome aboard

The lights you can find at your local marine store or online.

Hopefully someone with this model can tell you the prop size. Are they stamped with their size?

This size that someone else has, or what is supposed to be there is irrelevant. What matters is what size the OTHER prop is. Unless you plan on replacing them both at the same time, they will need to match. Go off of the size and pitch of the port prop.

I would also consider using the Mercruiser Prop Calculator:

The prop calculator is not geared towards inboards so I am not sure it will help.

hmm I see Outdrive and outboard only. I never noticed that before. Interesting. Then back to my original statement. The size and pitch should be stamped on the prop collar. I would go by that.
