At this point im just limping it through the last final month of boating season then gonna trailer it to my house and dig into it over winter

Well honestly mines not fixed yet. I pulled the outdrive off new impeller housing and wear plate also impeller. Same results i did recently notice the engine that over heats is not putting exhaust out the propeller like the other side so i must have a bad exhaust bellows maybe my problem is in...

Hey guys i found a 1980 srv 260 that has a full camper canvas i can't seem to find any details on dimensions for these tops. Do you think it would be interchangeable with my 78 srv 260 they look identical outside. Wondering if anyone on here has any experience with the tops?

Yes my apologies on the cooling system.. So on mine it comes from out drive into power steering cooler then through a cooler for the the charging system... IT IS A MERCRUISER 470 .. then into the exchanger and out the exhaust only place i have not been able to see inside of is electrical cooler...

Were you able to resolve this issue ??? Thanks

Thats good to know thanks

Its closed cooling system on mine. but i did replace the thermostat yesterday and exhaust manifold gaskets so i could inspect the mainifold cooling passages everything was clean as a whistle and the thermostat did not change anything

Not that new i just put new impellers in both outdrives my concern is parts of the old impellers are lodged in the cooling system somewhere. I tried back flushing system didnt see anything come out. it only over heats on plane above 2500 rpms and cools right back down below 2500 its obviously...

Darn i thought for sure i was a genius and figured it out lol thanks for the reply

Hey guys silly quick question. My assumption is when i hook the ear muffs to the out drive turn on the water. The water should flow through the raw water system and out with the boat not running correct?? Im having a overheat issue and just need to confirm there is a blockage in the outdrive thanks

Well thats exactly what i was thinking starting with the coolers and hoses is there a way to kinda back flush the cooling system. And also if i remove the caps on the raw water heat exchanger tube do i just have to replace the end cap seal or are those reusable ?

Well its not new to me this is my second year.. i rebuilt the impellers last year new gaskets and housings old impellers were started out of the water after sitting for a few years thanks to the previous owner smh!!! Needless to say there were pieces of the impeller i removed. Its done this...

Hey guys i have a 1978 srv 260 with twin 470s.. both engines run top knotch. My issue is with the cooling system one engine temperature gauge creeps up and up and up until i pull it back off plane. I can run them both at 2500 or less there fine as soon as it starts pushing water to plane it...

I will be replacing oil pan gasket and the starter I would hate to put a new one in considering the prices already had to pay 490 for the coupler plus shipping wooooooooooow!!!

Yea Dean to be honest the boat is brand new to me so it kind of gives me a little more knowledge toward the boat so if something happens on the water I have a better understanding how to get me home it's a great learning experience. Not to mention I only paid a thousand for the entire boat...

Awesome thanks man I will definatly use that resource How hard are the cam seals my engines have 700 hours on them if that matters

Well then... So tell me what did you use to pull the motor on ur 260 I'm thinking of building a 4x4 structure like a gantry. And yes defiantly replacing rear mounts. Does the outdrive have to come off to pull motor

You think the gunnels on a searay 260 is strong enough to hold that 470 weighs probably 700lbs scary

You got a regular engine hoist to go up that high the top of my transom is sitting at 8 feet 6 inches off the ground?? I was thinking toblay wood across the gunnels to lift it a couple inches and spin it

Yea that's exactly what I came up with thanks for the input. And I was lucky enough the po had the original shop manual for the boat so if been going through the procedures on all of it.. My trade is mechanic but on cars lol never pulled a boat engine but it looks pretty simple and strait...
