2784725<br />see photo links<br /><br /> http://tellico.off-road.com/wwwthreads_uploads/1261965-boat8.jpg <br /><br /> http://tellico.off-road.com/wwwthreads_uploads/1261966-boat9.jpg <br /><br />how much will it weigh, and how many cylinders?<br /><br />Im guessing late 60s, Mercs had electronic ignition in that vintage didnt they?<br /><br />what shold I check for after its been sitting for almost 2years? obviously it will need carbs cleaned and a water pump, and lower unit drain/refill, but what seals and such could give problems?<br /><br />thanks!

Judging by that red stripe it's a 68 - 71. I think that's a four cylinder. Weight about 200??<br /><br />They had a distributor CDI ignition, that's mostly electronic as there are no points.<br /><br />-W

I have a 69 Merc 800 and love it. The only thing I did when I purchased it was put a new seal kit on the lower unit, water pump and housing and decarbed the hell out of it. Runs great.

thanks guys, thats what I had guess, and what I had hoped.<br /><br />I guess it will have 2 carbs if its a 4 cylinder.<br /><br />are the hydraulic cylinders at the bottom for tilt and trim? that would be a nice bonus!<br /><br />It is supposed to have ran about a year ago, and then parked in the yard, its going to replace a worn out 50HP force, Ill bet it makes 3 times the power of a 50HP chrylser force motor.. haha<br /><br />Thanks again!

Re: what year is this 80 HP merc? now with serial#

I have the motor at home now, the serial number is 2784725<br /><br />it looks in rally good shape under the cowl, BUT almost very wire on th engine is corroded badly.<br /><br />the insulation is just falling off, and the copper is just green and pulls apart.<br /><br />i got it anyway, it was really cheap ( free!) so now I want to know if I should piece the wiring back together, or can I buy a harness?<br /><br />also, will a tilt and trim system from the same vintage 115 HP work on this engine?<br />the engine weighs a hair over 200, maybe 230 or so.<br /><br />Nathan,<br />I live in the historic district, behind what used to be Doc Murdocs<br /><br />thanks for all of the help and advice so far, Ill no doubt have alot more questions as I dig into this.
