Believed to be 78 Martinique

About a year ago my uncle told me I could have his old boat if I still wanted it. Its a Martinique that I believe is a 1978 model. I posted on here about a year ago when I found out but cannot find the original post. Long story short I am now getting to where I am going to start tinkering with.
I went and checked it over again last weekend and the engine mount bolts where snug and didn't turn, floor felt good. I first thing I want to do is see if I can get the motor to fire up as its been sitting for about 4 years. Unfortunately last weekend I did not think to take a picture of the engine or get numbers off of it.
My question to yall is what motor was normally in these boats. It had a 193, 187 or something like that on the valve cover. I apologize for the lack of information and any information I would be greatly appreciate.

Very nice boat, a picture of the motor would help. Could be a ford 302, 351 or Chevy 350. I am sure some one on her will have a good Idea of what it could be. Should be a fun boat.

I will get some pictures of the motor and numbers when I go back over there in a couple weeks. The other thing I noticed when I was looking over the boat is that on the back corner where the sun hits for most of the day the gel coat looks to be flaking. What would be the best remedy for this?

Somebody took that 351 you thought you were familiar with and turned it into a Small Block Chevy

The 198 Mercruiser was a 305 cu in Chevy engine

Yeah. I feel kind of silly now. My uncle swore up and down it had a ford motor in it. Was that a stock motor they put in these boats. Looking at the serial number it matches up to a late 70's

Good info including wiring and cooling flow diagrams

Update:
Got the boat off the lift and out of the water this weekend. Drained all the old fuel out of it and hooked a new battery up to make sure it would turn over.
The good news is the motor turned over good but it was a slow crank. I need to replace the battery cables as I found the positive cable had a bad splice in it. I believe this was causing the slow crank. Every thing else on the motor and inside of the boat looked good. I got new filters, oil and spark plugs for it I am going to swap out in a couple weekends.

I have a couple questions for y'all.
When I hooked up the new battery and turned the key to the on position the starter engaged and stayed engaged. Would this be a bad solenoid causing this?
And I have attached a picture of what the gel coat looks like on the back corner of the boat on one side. It looks like it is cracking and flaking. What is a good route to fix this?

I also attached a picture of the HID which i think confirms that it is a 1978 and also a nice surprise for me is that my uncle had what looks to be the original trailer and wheels for the boat.

If you happen to need a new solenoid(relay), since you have a Mercruiser Chevy BlueWater 198 engine, your remote solenoid(relay) is most likely different from the typical Ford solenoid usually talked about here on CCF and it's wired differently too

See page 20 of the manual in the link in the quote above for a wiring diagram

A picture of your solenoid showing the wiring connections would be good to help be sure of what you have though

Just spent a great deal of time looking at the electrical for a reason why my starter stayed cranking with the key off. It was fresh back from the rebuilder. Come to find out it was sticking engaged with the flywheel hence a mechanical issue. They are no fun to remove on the older wood boats as the engine needs to be lifted to service the starter.
Which has made the search very difficult.
