Help dropping lower unit

[nymack66]

I am assuming you absolutely sure all the bolts are removed, then it frozen on the upper splines place the boat in forward or reverse and grab the prop and rock it hard back and forth whilst a friend or help gently tap on the lower unit with a piece of wood and sledge hammer it will eventually drop please take your time and error on the side of patience.
Someone did not do a good job lubricating the shaft previously.

Weare going to try this tomorrow I was alone today. The guy I got the motor from said he had the water pump changed every year! Well he lied as the pump is weak, and won't come apart. and a few other things also say he was not as up on maintance as he lead me to belive!

O well Ihope things work out in the am!

Thanks

spammed again I see. MJ's been so worried about fixing his water pump that he missed this one. As far as the water pump goes, Mercurys won't pee good till the thermostats open up. But its good practice to change them out once a year or whenever susupect. You don't have to do anything to the shift linkage other than shift it in fwd gear. there is one nut on the fwd top side of the gear case, two nuts right under the cavitation plate, two nuts(one on each side) halfway back. Remove the trim tab and one bolt under it facing up. If it doean't want to come off, you can use a pry bar leveraged on the two studs that hold the lower unit on. Look for a small air gap to show up wgere the unit splits apart. You may have to use a screw driver to get the lower unit moving. They sometimes get stuck up where the alignment pins are. The fwd stud get stuck sometimes also. IS this a 20" motor with a 5" spacer?

Like they say; one pic is worth a thousand words...did you take pics of this project of yours?

I plan on dropping the lower end of my 150 OceanRunner looper and I'd like to see some pics of the top end shift linkage disconect.

Thanks

I have a 1994 and you have a pin that holds the shift lever in place (located on the front of the motor under the lower carbs). You pull out the pin and this allows the shift lever to slide back and forth so you can disconnect it from the shift rod. On mine I have to give it some throttle so the shift lever will not hit the lower carb. Its not a very hard job and I can have mine off in about 15 min. if I do not run into any problems. Mine is off now so I can replace the o rings which seal the unit where the shift ride enters the lower unit. They get corrosion aboud the orings pinching them against the shift rod making it stiff to use.
