alright so i need to change a hose fitting for the power trim on an old style black max.
does anyone know what size and thread type are mercury standard for trim hoses?
the rest of the boat has all the same size fittings- from the trim pump to the rams, i just need to know exactly what it is so i can oder something.
there is a leak at the end of the hose right before it screws into the ram manifold .
i know that most people here will say to change the whole hose.. and believe me i would but i will need to pull the whole motor for that.
the hose comes through the hull at the jack plate with a manifold that you have to remove the engine to get to. i have tried and there is just no way to get a wrench on it without pulling the engine.
so i disconnected it and cut off the bad part and im thinking i can use something like a brake line with some clamps. or perhaps a barbed fitting.
i have done this before on other hydraulic equipment, a small back hoe, and it worked for 2 years before i sold it and as far as i know still works fine.
i took the piece to the auto store in hopes to find something with the same size threads and i guess i must have went on short bus day because the guy just kept asking me what year car i had... i tried to explain that i just needed a standard hydraulic fitting - a piece of brake line with a flare fitting the same size as the one i had in my hand... he said "we dont carry boat parts"
my frustration was high.. my patience was low after fighting this fitting for an hour so i left.
im trying to find the size fitting i need so i can just order it.. is it OD, compression style? 1/4 inch - 5/16 - 3/8 - ?
these are questions i am sure some one has the answer to.
let me again state that i am just trying to "jury rig" something up to avoid removing the engine until i absolutely have to.
i know the risks of using non standard equipment, and splicing a high pressure hydraulic hose, but like i said - i have done it before and had excellent results.
i have attached a picture for reference. the rusted one was obviously the one leaking and the leak is right near the end - i have a good clean cut and can slide a piece of brake line or barbed fitting 3 or so inches up into the hose so i can get a good bite with 2 hose clamps.
