Very happy to be here after years lurking! Bought my first Grady this week, a 1986 Overnighter 205 I/O. It's actually the 10th boat I've owned, and the 3rd I currently own, so I'm not new to boats. I've been a fan of Grady's for a long time, having lived in Greenville for years and going through the factory a couple of times. However, there are some things with this boat that I don't understand and so I need to reach out to some experts...

First I checked the transom and floors. All solid except the port side corner near the stern is soft in the floor, and the starboard side is slightly soft. Will deal with that later. Plan to get the tank pressure tested later too. The outdrive is off the gimbal, so I've got to get that reinstalled. However, my big "to do or not to do" question on whether to tackle this project lies in the engine compartment.

Looks like the original engine may have been swapped out for another 3.0L Mercruiser, and the Alpha One Gen 1 gimbal housing and outdrive looks to possibly have been swapped for a newer one also. However, I'm thinking this is all the same type of stuff it was equipped with originally, so it hasn't been too heavily modified I don't think... I don't have much backstory, but it appears to have been mid-project when someone ran out of time or money. The oil in the engine looks brand new as do some parts. I'm thinking it was in the process of re-assembly, and I plan to pick up there with a new gimbal bearing, bellows, impeller, and so on as it's re-assembled. However, I noticed something strange and disturbing...

The engine isn't sitting on the original mounts. It appears there are two large studs on either side of the block mounted to pillars down in the hull to support the weight, but these are just sitting there not being used. Instead, the engine is bolted to an A-frame looking contraption that is resting on a stringer and not even bolted to it. It would seem that instead of using whatever type of frame that would have been required to couple this engine to the original studs, this frame idea was implemented. So here are my questions:

Does anyone have a pics of what the original setup would have looked like?

Would using this setup be an issue? (I worry that stringer isn't designed to hold the weight, and the frame bolts holding it up look a bit sketchy. Moreover I don't like drilling into stringers.)

If I look aft toward the gimbal housing from inside, under the engine, I can see the exposed flywheel. Is this normal? (Seems like there should be a cover, or maybe this is some sort of unholy marriage of engine and outdrive.)

Any help at all would be appreciated! Now to try and post some pics, both some obligatory "New boat, first Grady" pics out of excitement, then some pics of the areas in question. Thanks again!

I guess I’m going to take this thing to a shop tomorrow and hope I don’t get taken advantage of too badly. I think I’ll start a separate post though about the fly wheel; maybe that will pique someone’s interest and they will respond.

Wrong engine. The boat probably had a 260 Mercruiser in it.

Yes, it's normal to see the flywheel (from the right angle).

Your boat originally had a V6 or V8 - those (currently) unused motor mounts on either side of the engine are for a V6/V8. So it looks like there is an adapter kit to use the 4-cylinder. That A-frame part is the correct piece for a 4cyl - but it will normally bolt tightly to the block instead of using those long bolts you have there. But maybe with the "kit" that's what you get. Or, maybe it would be better to glass in a new transverse stringer to mount the A-frame mount directly. Either way, yes, it should be bolted down. As you surmised, you've got something that is "somewhere" in the middle of a rebuild.

Just a quick heads up... my boat was swapped to an outboard, but the original cutout where the engine would be was never sealed and it led to two, small areas that were soft (similar to what you are talking about). The wood/area that is soft WILL be much larger than you think it is. The "messy" (second) picture is one I took part way through my rebuild. Just throwing these in there "for fun" and what you "might" be getting yourself into. Hopefully not, though!

FYI... don't be too quick to assume that people won't respond to your posts... we all have "real" lives other than this forum! Good things come to those that wait.

This is very helpful, thank you guys so much! I was wondering if maybe it had a larger V motor in there; would make sense with those studs where they are. It’s also a big relief to hear about the flywheel situation!

Adding a stringer and bringing the A frame up against the motor is a great idea! It looks sketchy dangling from those bolts, but being up against the motor should be plenty strong. PlusI I won’t have to drill the factory stringer.

Looks like you had a nice result when you finished your project! Hoping I won’t have to go that far. I had considered doing a similar project and converting to an outboard on a bracket, but I don’t wanna put that kind of time and money into this.

Thanks again for the replies and sorry if I was impatient. I was nervous about taking this thing in and getting taken for a ride. I’ve got a # in mind for how much I’m willing to invest in this thing. If the estimate comes out greater than that, I’m going to pass and sell this to someone else that has the skill set to do the work and the desire to invest in it. I like this boat on a trailer, but I suspect I would prefer the Seafarer in the water so I’m torn… I have about 300mi one way to my fishing spots, so the lighter / smaller Overnighter has its advantages!

A call to Grady with your hull ID #, you may be able to find out what was in the boat originally.
