new prop

[JIMBOB]

Tryed to get my engine sorted today,I took my prop down to prop rev and they took one look at it and said I needed a new one!

but it wasent all bad. they sold me a prop from Turning Point Props called"rascal" its a kind of mix and match idea you buy a hub then your required prop seperate.

then your ready to go ,that cost

James,

 

I got a new prop today as well. Bog standard 9.9 inch X 9 inch and also around

Hi paul

My props 10~3/8 diameter x 11 pitch ,There quite a difference from yours,

Is your orkney a semi dispacement hull? Taras a planeing.

James

[Paul D]

James,

 

Orkney is a semi-displacement hull also the pitch will depend upon the ratio of the gearbox in the engine. ( I had previously a prop with a pitch of 9 3/4", so I have reduced the pitch by 3/4 " which should mean higher revs for the engine. )

 

Acid test will be to take to the water.

Hi paul

Just abit of info regarding pitch,"for every 2" of pitch, RPM's will change approximatley 400 RPM's" So you should have about 200 more RPM's

James

James,

 

I was expecting more like 400 RPM ( as in 500 RPM per inch ). Surely the increase will depend on the gearing of the engine ? ( Mine is 2.08 ).

James, I hear that mercury are looking for a highly skilled engine technician to tweak the finer adjustments on their new engines following a multimillion pound cash injection into the project........................with hammer mighty firmly in hand, the application is in

Managed a short test run yesterday,with the new prop, Its looking good managed 16 knots with 3 adults and a nipper on board (dosent sound a lot but with 3 adults tara normally only does 12 to 14). so I cant wait for the first outing with only 2 on board
