Hello,
I 'm repairing the power trim -tilt rams of the above engine that are leaking oil and i noticed that the trim ram seals don't have internally scrapers in comparison with the tilt ram.Is this normal? If the debris gets on the trim shafts won't it harm their seal very soon?
Hello everybody,
My Mercury with only 180 hours on it some time ago started a noise something like a shot bearing mostly recognised at idle rpm.When i took the boat out and run the engine on muffs the noise was much louder almost sure that something was broken at the height above the lower...
Hi all,
I 've found an outboard Mercury efi 225hp at a very good price and i wonder what would be the efficiency of my old (1978) Sea Ray SRV 220 if i replace the mercruiser 228hp inboard (around 30 knots) with the 225hp outboard adding a bracket.Please don't suggest me to keep the inboard...

Hello everybody,
May somebody tell me which one is better? Does the mercury will give me significantly more hp? which one is more reliable? I' ve heard that the new outboard engines usually have problems and need aythorised technicians for the service because tuning an mpi engine needs special...
In general i know the head torque for GM350 is 65lbs but the service manual #9 says that some models refered as "performance production" models take 75 lbs.My gm350 has block casting number 10243880 with the 14096217 (64cc 285/300hp for 12bolt intake, the center bolts at 72").I wonder if the...
Hello everybody,
Two years ago i bought a new gm350 base marine engine.I 'm replacing the head gaskets due to overheating.In fact this engine has never worked at WOT properly without cooling problems although i replaced almost every part of the cooling system (raw water).The whole setup is that...
when i was adjusting the valves of my engine (i bought the block with heads new last year but hasn't still worked properly) i find out that at three cylinders when i was adjusting the nut 1 turn back the compression was lower.Doing a leakdown test i find out that the leak stopped at 1/2 to 1/4...
Sea Ray 220cc 1978.previously had pre-alpha outdrive MC-1 with gm305 carburated,now it has SE106 outdrive with gm350 with the fast burn heads(64cc 200-210psi) NEVER HAS WORKED PROPERLY.A week ago when idling at the dock i noticed drops of water exiting the starboard cylinders.Since the block...
I 'm going to replace my intake manifold at my gm 350 (old style - carburated, 12 bolts) and i'm wandering a) if there is a difference between the two metals for fresh salt water use and b)can you suggest me a reliable site that sends internationally and to be sure that it will be brand new and...
Hi all, i own a 30Hp Mercury (ONO34545 2004 MA30ML) and my problem is that even when i bought it brand new i had to pull 5 to 10 times the rope to start it up for first time.The only thing i can imagine that could make a difference is a different spark? The sparks it uses are the NGK BR7HS 10.Do...
Does anybody here knows if the following not-vortec heads (14096217... 55-86...350..........Crate motor, 285hp/300hp, 64cc chambers) take the same spark plugs with the same gap as the mercruiser mcm 260 5.7l (Champion rv8c gap 0.035)?
-rochester carb,delco est ignition-
Although the carb was rebuilt three years ago by a car mechanic now that i decided to rebuilt it myself i found that the two screws at the throtle body were significantly loose.I noticed also that they didn't have the washer that forbids loosening ( sorry i don't know how it's called) in...
Hello everybody
1)a mercruiser dealer told me to use no sealant at all when installing the new gaskets.Not even a thin film round the water passages? (i know that the gaskets are embedded with sealants but when taking off the gaskets of my 350 with only 10 hours of operation i noticed that the...
