What Engine size?

[jorgeinmiami]

What engine are most running on a 20 MA open.
I've seen up to 200 but that may be a little to much.
My MA is rated to a 175 but those are not as numerous as the 200's or 150's.
And I have owned mostly Evinrudes but had Mercury EFI and A Yamaha 200 saltwater and was happy with both.
I have also notice that a lot of used engines come in a 25 inch shaft which also limits the selection.
And I know that weight is an issue unless I raise the transom

So what would you think would be the "best" choices

130 Yamaha, DT140 Suzuki, Mercury/Mariner 2.4/2.5L V6, or inline 6cyl 140. That keeps your engine weight in the 280-340 lb range.

Would love to have either a 150 Merc EFI or Yami.

But my wish list would be an E-Tech 150-175 but $$$$ not there.

I wonder what kind of performance I would get with the 130 vs the 150's ?

I know I can get by with a smaller engine but I do have to teenagers that want to wakeboard and such. Also when you load up the boat with a couple of my fat buddies (me included) and the gear I want the ponies to go with it

The 150(165) E-Tec will get you close to 50 with a light load; the 130 should run low 40's. Although I'm partial to the lighter engines like Fr. Frank, with 4 folks and 4 sets of dive gear and tanks on my Seafari in the Keys last week I was glad to have the extra omph of the V-6!

I posted this info in a different forum, but the USCG (not the mfg) recommended max HP rating of a 20MA is 230 hp. Add a swim platform and it jumps to 250 hp.

The formula for a single engine is (LxWx2)-90= max recommended HP. Max HP is always rounded up to next higher 5 hp increment.
Length is LOA, (including permanently mounted fixtures or accessories) rounded up to the next higher foot. Width is beam at widest point, rounded up to the next highest foot.

If your transom is 30" or if you have a bracket behind a closed transom, the multiplier for single engines is 2.5 instead of 2.

If you have twin engines, the formula is (LxWx3)-50= max HP. This is why the early Potter-era 23'3" Seacraft CC twin OB hull had a max HP rating of 500 hp, later reduced to 400. The new 23's are mfg rated for 300 hp max

So with a bracket

I'm in the same predicament as you except I won't be making a purchase for atleast another year. I have narrowed mine down to three choices. I used to work on outboards years ago when they were all carbed and 4-stroke outboards didn't exsist (to my knowledge). All these new outboards scare me with all the hi-tech electronics they have now. I miss the days when all that went wrong was a coil or a power pac for the most part.

Top choice is a 150 E-tech just because I love 2-strokes and have allways loved Evinrudes. They seem to be great engines and I love the low maintenance. They seem to be pretty pricey from wht I have seen online though. I would still consider the 130 E-tech I am just scared it won't be enough. I have been brought up that a boat should be overpowered just in case you need it to get out of harms way and I have 2 sons that will want to do some skiing and other water activities.
My second choice is the 150 Yamaha 2-stroke. Not the HPDI but the carbed motor. According to their website and brochure they still make them. The cost from what I have seen is thousands less than the E-tech's. I know they are thirsty motors but the old school technology is very reliable and I am not drastically conscerned with fuel economy as I will only be able to use the boat a few times a month.
My third choice is a surprise to myself because I really do not like 4-stroke outboards(too many moving parts) but the Suzuki's impress me. I am very seriously concidering the DF140. It is a few pounds lighter than my first 2 choices and I think would make a great motor for the 20MA. I would of never conscidered a Suzuki but I have a couple friends that have them. They beat the crap out of those motors with Zero issues so-far.

i'm running a new 150 yamaha carb motor. i don't think you'll be dissapointed with fuel economy

[Basspond]

150 Ox66 Yamaha on my 20. I think the 150 range of HP is the perfect match for the 20.

My MA loves its old carbed OMC 175. Transom redone but not raised. Seriously considering enclosing, Hermco bracket and 5" extension because this 1999 only has 140 original hours. Very nice combination as she sits. Part II.

[jorgeinmiami]

From the little I've seen I think it's going to be either a Yami 150/200 or a Merc 150/200 EFI. I know the the rudes/johnson have had issues and I'm not sure which are good or bad so.....

But I am just doing homework on it
