errm im not sure as im only going of the dreamo guage,, i dont have a tach..

so ur more like 65 mph?
you need a tach atleast. a gps would help
if i was you get rec head or urs cut. 14/20 impeller and advent ignition.
if you get ur plate cut by jim or island it should yield a couple mph. but ur in the sea so i dno how much it will help.

You need a good tach in order to tune a 2 stroke..

Take out the freeflow and put your stock sound suppression back in.

all my speeds were recorded by gps... i dont have the outright cash to go massive gains,,, i do have a protec turbo pipe coming from pistonwash will this help?
im just looking for good pointers from people to get a few more mph.. i would be willing to spend a couple of hundred £
ive got my pump off now and someone is relining my ring and going to repitch my prop.. what pitch is best to go to to get more top end?

look on flee bay for a tiny tach if you cant afford a pet 2100 ther about £60 over here and ok for now untill you get sorted a pet
your turbo pipe is best suited to bottom end work not sure if there is a loss on top with one,you gotta ask about,
take the ff out stock ss for top end
remove the extended trim tabs for more speed,i scrubbed .7 mph with them on,even my rough water boat dont run them extended i just space them if needed
