Re: prop numbers

We need to know more about the parameters that affects prop choise:<br /><br />Boat make and model, weight (ready-to-go), width and how you use it? What kind of sea bottom is there at you normal sailing area?<br />Motor: Year, what rpm do you reach at WOT, what size/number is on the old prop?<br /><br />Upgrade: What are you looking for? Top speed or hole shot?<br /><br />Budget: Stainless is 2-4 times the price of alu or composite (roughly). What is your preference?

Re: prop numbers

The ol' props ID is on the forward end of the props hub so when you remove the prop, it'll be visible.<br /><br />Best guess so far would be a 17" pitch prop. <br /><br />Still, the other info is important to point out the right one.
