So I recently had our boat fixed. And it is stronger then ever due to the timer base being sticky for several years. My question in regards to my current prop is weather or not a new prop of the same size is in order. Or a decent ss. The current 20 year old aluminum omc 13 1/4 x 17p is a little banged up here and there. Nothing to overly serious. But a few small pieces here and there missing . As well as some mild wear. The engine will turn the prop to 5600-5700 rpm at 44 to 45 mph. I have read some on here say 5500 rpm and some say 5800 rpm for the v4 crossflow. I am near the upper end of the two numbers. I am NOT looking for anymore extra speed. The boat is fast enough as is. My question remains as to weather or not my rpm at wot is good. I assume so . And if I was to purchase a new prop. Should it be ss or aluminum ? And what differences would I see in the two ? Thanks all .
