Mercury 80hp Outboard Engine Start up after winter layup - Winner Cobra Speedboat

First Start up of the season after Merc 80 hp had been winterised. Produces plenty of smoke while burning off the fogging oil but clears and runs well, hopefully will continue to be the best outboard I've ever had! This Mercury 80hp is fitted to Classic 1979 Winner Cobra Speedboat - Fully restored example - based in UK

hi, just wanted to ask. what is your idle speed when in the water, i have the same motor running a lazer 20p stainless prop. i have to idle mine at 1500rpm just to put it in foward gear for slow moving.

thanks

[burrow70]

Sorry for delay in answer!, 1200rpm!

[burrow70]

Oh yes,

[wilzchau]

Will it pollute the water because I saw exhaust coming out from the prop.

[burrow70]

Thats why the industry move to 4 stroke. But you know, the amount I use this boat I don't feel that I am harming too much... Better I had an economical 2-stoke that a 350 magnum V8....

Can't beat a good ol' Merc!

The prop's not turning...does the engine have a clutch?

[kscorer2]

out boards dont have a clutch the prop spins in neutral if it hits some thing it will stop spinning

[kscorer2]

@insecure53 Yes the motor has a clutch. At 2:12 he puts it in gear and then takes it out of gear a few seconds later

Mannnn......this motor sounds very well taken care of. "nice job"

[insecure53]

@gsxrfrk85 I know, I found out that these things have clutches and gears right after I made that comment...two years ago. Before that, I always thought outboard props spun freely (at a slow speed) while idling.

[gsxrfrk85]

I have a question, what kind of prop is that?

[gsxrfrk85]

@insecure53 umm, that's because it's not in gear!! LMAO

@6speeddakota, actually, the forward and reverse gears are constantly engaged with the pinion gear, the prop shaft is splined in the middle with a clutch on it that moves to either engage either the forward or reverse gear, the grinding noise is the clutch slipping not the actual gear teeth, shifting should be done in a smooth, quick manner to reduce the grinding and wear on the clutch dog
