Thanks for that, I will give Hamble propellers a call, I did think of Fairweather as I live 5 mins from them but when I googled them they don't deal with Mercury's.

It's on a Merry fisher Marlin 6 and I'm running a 100hp Mercury. She will plane empty and achieve 25kts, I would have thought with the 100hp I should get a little bit less than the rated 25kts with a 100hp. It's as soon as I load it with gear that I am at nearly full throttle to get it planning. I am contemplating a 4 bladed prop as well.

is it a 2 stroke motor or a 4 stroke 13.25x17 will be the next size down and will prob get you into the lower recommended rpm range or 15 pitch for more, also alloy or stainless prop 
if you have to measure it, its too small!!

Hi Billy

It is a four stroke and I am going to stick with an alloy prop.

Did some test runs on Saturday,

Engine rated at 5000-6000 rpm WOT

With 2 adults and some but not all of my gear on board we achieved 4700rpm, My normal running configuration would be with another large adult and the associated gear on board.

Personally I think she has been propped for top end speed as the guy who I purchased form had hardly any gear and fished solo most of the time.

For me I will 2-3 anglers at all times and we have a fair amount of gear.

I want to achieve a quicker plane time and good cruise performance as this is what she will spend 99% of her time doing.

99% sure I am going to go down the 4 blade prop route.

been playing with props on mine and have made the decision to have a alloy re pitched to a 13 1/2 x 18 with a bit of rake as well, am hoping it will be the perfect set up then Big smile

She is currently running a 19" but after speaking to Hamble propellers and the local Mercury dealer, to get the RPM right I need a 15"-16" pitch.

Unfortunately the 4 bladed props available off the shelf are either 17" or 14" either too little or too much, so after much deliberation I am going to go with a larger diameter 3 bladed prop of 15" pitch.

Actual size being 15.5x15

Just a thought do you have trim tabs fitted, going back to my day of fast motor boating I was advised to to fit them and it made all the difference with getting on the plane quickly and keeping the boat level.
