Re: mercruiser 165

dude<br />I wont say a word about the rubber fuel line. I think you know what we all will say<br /> good luck and hope the hose never chafes or leaks.

Re: mercruiser 165

What is the rubber hose between the manifold and the fire thingy(excuse the lack of knowledge on the terms)? Mine just has a hole that you can see straight down inside the motor. My boat has the same exact motor, it was replaced in 2001. I have owned my boat for a little over a year now. We use it quite a bit and I never considered it a problem. Is there any cause for concern? Does this affect the motors performance?

Re: mercruiser 165

hello<br /> the tube between the choke housing and the manifold is a hot air pipe for the choke. if your refering to the breather tube from the rocker cover to the flame arrestor it aids in venting blowby gasses to the carb so the incoming air will suck it back down. you really should replace it. I was refering to the rubber line between the fuel pump and carb. at 6-7 psi it does not take much of a leak for bad things to happen.<br /> good luck and keep posting

Re: mercruiser 165

Guys.... wait a minute... Let me explain: The last photo (the one taken directly at the 165 engine) shows the old metal fuel line. It later cracked and leaked, roughly 2 summers ago. I got hold of a buddy (also a certified mechanic) and instead of ordering a whole new Merc fuel line, he recommended replacing it with a heavy duty, high pressure, fuel line, which clamps into a GM fuel filter that is made for the 2bbl Rochester carb. I know what you are thinking.... But the fuel line is very sturdy, heavy gauge, and yet flexible. It will not fray or chafe.<br /><br />Butch A.

Re: mercruiser 165

Joe99,<br /><br />I can grab a digital camera from my office, and snap a photo or two of my starter, distributor coil, etc... and then post them up. (the other photos of my 165 were taken with my old classic Canon A-1 35mm SLR).<br /><br />Butch A.

Re: mercruiser 165

Each hose clamp on a hose from the fuel tank to the fuel inlet <br />connection on the engine, a hose between the fuel pump and the <br />carburetor, or a vent line must:<br /> (a) Be used with hose designed for clamps;<br /> (b) [Reserved]<br /> (c) Be beyond the bead, flare, or over the serrations of the mating <br />spud, pipe, or hose fitting; and<br /> (d) Not depend solely on the spring tension of the clamp for <br />compressive force.<br /><br /><br />(D) pretty much sounds like hose clamps are not allowed on the pressure side of the pump<br /><br />tommays
