    Clanton, Information on Tilt/Trim Pump

    Here is a question for you. I have called a machine shop here and they say they don't know if they would be able to rethread the Hydraulic lines into the bottom of the pump. Do you think this is feasable, since you did say that you were about to have to do a few pumps there? He said something...

    Fuel pump diaphragm

    I just checked my fuel pump diaphragm and it seems to be stretched some. I am going to go ahead and replace this. The question I have is could this allow me not to get full RPM's?<br /><br />Thanks for any info,<br /><br />Bryan Cox

    Would this cause WOT not to achieve higher RPM's?

    The engine is an 88 Force 125HP. I can get up to about 4900-5000 RPM's at WOT trimmed out with a Hustler 13 1/4 X 17 Pitch prop. I'm wondering if the fuel Diaphragm could cause me not to get up to about 5500 RPM's? I have never changed this and have had the boat for about 5 years. It did sit...

    What would this do?

    I am wondering on the way that the air vents into my engine. The only vent is located at the top backside of my cowling, on an 88 Force 125 HP engine. I am wondering if I made a cut out in the front side, sorta like Ram air on a motorcycle, what would this do? There is no air filters on this...

    How do you know if your running too Rich?

    I have a friend who is a boat/Jetski/Motorcycle mechanic and he has told me to make sure that I run my Force 125 HP rich. I had installed Boyeson reeds, which they say to add 1- 1 1/4 turns richer to the mixture, when they are installed on this engine. I now have my mixture screws set at about...
