What year is the motor?

[jerkoz]

no exactly sure of the year. will check the numbers and get to you.

The pitch and diameter should be stamped on the barrel of the hub. If not you can measure the diameter with a tape from the center to the end of one of the blades and then double it. As for the pitch, a prop shop will have to measure that for you. There are ways you can do it, but they are very involved and are usually not right anyway.

If through hub exhaust the numbers may appear near the base of the blades or under the prop nut.

The motor is a 1986 50 h.p. Vro model #e50belcde

Prop numbers should appear near the base of the blades or under ther prop nut.
If your thinking replacement it should be based on your present performance and prop size.
Read "read thes first" at the top of the page and get us as much info as possible.

12-1/4 x 15P is a very typical prop for that size boat and that motor. 11-3/4 x 17 is another possibility but those two are the most common.

Hows she running with that 50hp? I have a 16' Starcraft Fishmaster (Aluminum) with a 65hp Merc and she flies! Oh and by the way I am running a 16p prop, just FYI.
