mariner 25hp 2 stroke

[uny1965]

hi all, with regards to my early xmas present, (25hp mariner 2 stroke) I fired her up yesterday on single sided flush muffs, and noticed the stream of water from the tell tale was pretty weak and rather warmer than usual.

Is this normal ?

Stream is a lot stronger when submerged in my wheelie bin, but I dont fancy lifting 51kg into a wheelie bin everytime I flush it out.
Am i doing something wrong, my tohatsu is no problem on the same flush muff.

regards. paul.

btw thanks b&o for the quick response regards the kill cord

turn the tap on a bit more?. my old 75hp mariner barely had a tale tell on a hose unless i cranked the tap right up. i had the bottom off it quite a few times as better safe than sorry and everytime i done it the impeller was fine and outboard worked when in the water.

cheers

Thermostat

Those models tend to pump as and when needed rather than a constant cool flow

Unless is an EX MoD one (there are hundreds knocking about) The cooling system is modified to have a colder tell tale so it runs all the time. You can tell the Ex MoD ones as the tell tale comes from the exhaust cover on the block instead of the top of the Thermostat housing.

True, but I'm not sure if they were still in commission in 2006 when this one was made ?

Yeah, MoD had them from about 1995/6 and they still use them today (although the engine went out of production in late 2008.

Out of interest how were they modified ? Did the stat get replaced with a washer etc to restrict the flow ?

Does that mean only one intake port is getting water?

or is there only one intake port on this engine?
