1988 skeeter

[Jordan09]

I have a 1988 skeeter bass boat and the title says that it is a 50 horse mercury motor but I can’t find the tags to find model number or serial number on it. It seems to be taken off, is there another way to identify the motor?

Anything would be helpful in identifying the motor

On some engines there is an aluminum tag about the size of a quarter embedded in the left (Port) side of the engine block. Easy to see as everything is black on the block but this silver tag. Is the engine a 4 cylinder 2 stroker? If so, it will be in the range of 40-50 HP.

No I’m not new to boating. It is a 3 cylinder, 2 stroke.

Best I can do is a '94 sales brochure showing 50 and 60 hp engines being 3 cyls with 51.8 cu. in Loop Charged powerhead, 5k to 5.5k WOT rpm range, 16 amp stator, 1.64:1 gearbox, 10" wheel, 207#.....going to guess this design originated back in mid 80's time frame, maybe earlier. Prior to that the 4 cyl had moved up from original cross flow Mark 55 40 hp to 50 and back to 45 and then 40 don't know the time line on all that but the 3 cyl was Mercs new lost foam Loop design and covered the mid range engines. You still probably have the tag I mentioned.

Yes, like some photos.

All you've given us so far is that its a3 cylinder 2 stroke outboard.

Here are some pictures

What's written on the tag on the left of your first picture?

“This Engine has passed a Factory Test by ....”

It is a newer than mid 80s.
It has so much stuff bolted on it is next to impossible to see if has 2 or 3 carbs. Looking at the rear of the engine, and at the Midsection, I am certain it is not a Looper, but rather a late 80s/early 90s 50 hp or 60 hp, based on the 49.7 cu” block

I was able to scrape the paint of the sticker on the mount and got serial number 08343674. Those are the numbers I could read and I think that’s all of them and I believe those are the right ones.

I also pulled the carbs off today. There are 2

East to tell if it's a looper or original design off the Mark 55 4 cyl....pull a plug and look at the piston crown. If flat it's a new block design. If crowned, a cross flow like the originals. I remember back there somewhere merc had a 35 twin cross flow, just took half the cylinders of the Mark 55.

I guess you are looking for parts. If you can't figure it out, test the water from a supplier where you can return the parts if they don't fit-look like the parts in your engine....gotta leave them in the original baggage and condition so that seller can put them back up for resale to get credit. Good luck.

I believe it is a 1050412BD elpto

No 3 cylinder would have Pistons that look like the Pistons from a Mark 55. They would either be flat tops if looper, or a the Eyebrow deflector in the case of a Direct Charge engine, of which I am 99.99% certain this one is

More Evidence of that is the 2 carbs, a 3 cylinder Looper would have 3 carbs, and a much different midsection

 

[Jordan09]

The pistons are crowned which is the same as the parts for the 1050412BD elpto
