Are they broken? Stock reeds almost never break.

The guy at the dealer, who went through the motor and kitted the carbs and serviced it after it had sat for a few years, said they were "bad" and would cost $1000 to fix. The compression is 150-160 on all 4 cylinders and the motor LOOKS pristine. You Tube makes the job of changing the reeds seem do-able and not worth $1000.

Why do you think reeds bad?? From your old post it looks as it it runs fine. The engine will need to be disassembled to replace reeds and its about a 8 on a 1-10 list. If it runs fine as you stated leave it alone........

I have an '86 Mercury 75 hp outboard that I bought last Fall. I had the carbs cleaned as the boat had sat for 2-3 years without being started. I hooked it up to muffs and the engine starts right up and runs smooth as silk. I ran it for 30 minutes at different speeds and had on problems at all

Its a lot harder than you think it is. Its an old design that seemed to be designed to be difficult to change the reeds. The whole motor needs to come apart. Having said that its extremely unlikely that they are bad. Reeds almost never go bad. $1000 from a shop would be a bargain for that job if they actually were bad which they are probably not. Unlikely it will make any difference changing them. Find a mechanic who knows inline mercs. They aren't like modern motors and you need someone who really knows them. Dealerships don't train people to work on that stuff any more and your mechanic might just be leading you down the road to changing parts willy nilly at your expense. It happens all the time.

Boyesen reeds don't really work all that well in inline Mercurys

All I know is what the guy at the dealership told me. This is a reputable place and I have known the man casually for several years. The motor fires right up and does run fine in my driveway. The dealer said the motor was not dependable if the reeds are bad so I have been scared to get it in the river. When I took it to the dealer it was to have the carbs checked....I would pump the bulb and it would never feel firm and gas would run out of the engine. He kitted the carbs and fuel pump, ran new fuel lines outside and in, new plugs, filters and lower unit oil. He called me and said it wasnt running right and never would because the reeds were bad. So you think I should just put it in the water and use it as is?

Thank you so very much for the information and link to the diagram. I can see from the picture why changing the reeds would not be anything like the job shown on You Tube.

Is there anything that could be mistaken for bad reeds? I dont think this dealer is purposely lying to me....he seemed pretty sure that after he had done all the work, the reeds were bad. Dont know if it makes a difference but the compression is 150-160 on all 4 cylinders.

Carbs, especially the off idle transition to full throttle. Lots of timing adjustments in the linkage that need to be correct. Ignition timing, fuel pressure, float levels. The labyrinth reed blocks themselves. Real hokey way those reeds are installed straddling the crank. Reeds themselves are pretty durable and dont do much over about mid throttle.

1st off, why do you think theres a problem? Your compression is better than good. is it bogging off idle?

Re: Where can I buy Mercury Reed valves for 1986 4 cly 75 hp?

If he didnt take it to the lake and try to adjust max advance timing, idle adjustments , and or max throttle then id ask him to try it unless they have a test tank in the shop with test props ??? I jsut went through this on my 65 650 merc and turns out may have just been fuel tank vent closed up on me , it will cause primer bulb to go flat ... I also did fuel pump etc...if hes done all that i would think hed know that timing link n sync is very important on these motors and there all different ...Just a thought ??
