how to pull inboard motor

[bizybily]

I just picked up a 1969 19 foot North American with what i think is a gm 153 I /L4 inline 4 cylinder, that has a hole in the oil pan. Can I pull this motor without removing the mercruiser outer drive. Also any tips on the job would be appreciated.

pull the drive first, remove the front lags ,remove the 2 rear bolts, lift up and out, R/R pan, reverse assembly

Stop now and don't spend another moment of your time on it. OK, you probably won't take that good advice so yes you must pull the drive off. A 19 foot boat with a 4 banger must be a looooong day on the water. Count on trashing the entire power package as it will need more money dumped into it than it can possibly be worth. I hope you are going to repower with a V8 and a bravo 3 so that you can actually plane.

Hold on a second...Not sure what this boat is like, but my 19 foot Bayliner was a jewel with its 3 liter, four cylinder. (Furthermore, there's THOUSANDS of boats this size out there with the same engines.)

But--there's always a "but"--if this boat of yours is a massive, heavy hull for its size, then all bets are off.

Its a 1969 19 foot North American built in Florida. Don't know what o2batsea is referring to but the boat does fine in the water. Ive pulled many car and truck motors but no experience with i/o boats. Could sure use some constructive help. I'm soon to be 75 years old and want this to be as easy as possible. Pretty much Greek to me

Consider changing the rear main seal and oil pump while the pan is off. Inspect the drive coupler and ring gear for the flywheel? You want to address any issues you can find so you dont have to go back any time soon!

Yes, you can pull the engine with the drive still attached.
You will need to slide the engine forward enough to disengage the universal drive shaft from the drive engine's drive coupler.

However, when re-installing the engine, the drive will need to be removed or you will be fighting the shaft-to-coupler engagement.

Don't forget that with a gimbal suspension system, you must perform the coupler/engine alignment after the engine is installed.

ans dont sweat pulling the drive, its a piece of cake. put the drive in forward, unbolt the rams, unbolt the 6 5/8 nuts and the drive should come right off.
