help with motor selection
I have been doing some book work on my 72 Grady project, trying to plan ahead for the motor install, but I'm stuck on the single or dual outboard delima. My plan is to try and get at least 250 h.p on this transom, its rated for 245 on the tag. I know once I install the 1 1/2 coosa bluewater in her she will hold alittle more. I have given a lot of thought about the weight of the bracket also, most i have seen range from 115-140 lbs. depending on the application. I will stay away from a heavy 4 stroke if i have to, but i don't want to sacrifice eff. and speed tooo much! Right now the boat weighs about 2400 lbs with the inline 6 and OMC outdrive, it is a walk around cuddy cabin, and is built really, really well to accept a bracket. Any Help?

A single DF-250 Suzzy.

I know you run dual suzzies on the X-SHARK wart, but makes you chose the single 250?

240lbs less weight. I belive the fuel milage may improve more also with the single.

That would also be my choice. The Suzi runs a larger gearcase, larger dia. prop, and oil bath chain drive camshaft. Both it and tha Yam. 250 4s run variable valve timing but the Yam. has a rubber belt. Just my $.02

Re: help with motor selection
All the high pressure injection outboards out there right now- Merc Optimax, Yami HPDI, E-TEC, are a lot lighter, cheaper, and get out of the hole faster than a 4 stroke- If you really check the gas milege numbers, the 4 strokes dont beat them by that much- in my mind not enough to spend the extra $$$$.

Re: help with motor selection
The Yamaha HDPI would not be on any list of mine.
You forgot to add $15 to $20 for oil for every 50gal of gas you burn. That add's a bunch to operation cost's. You've never been in a Suzuki powered boat have you? Most all people that make statement's about poor holeshot are talking about 4 stroke Yamaha's. You have to pry the imfo out of them usually as to what manafacture motor they have seen perform. It's in the gear ratio and size prop they swing on a Suzzy that gives just one advantage over other 4 stroke's. There are more. |

Somebody would have a tough time convincing me I should have a smoking 2-stroke on the transom becuase they are 20#s lighter and have mileage that is "almost" as good as a 4-stroke. |

Re: help with motor selection
I have never seen a puff of smoke from my 225 Opti- looked at 225 4 stroke Yami- was $4,000 more and weighs almost 100 lbs more- also got 5yr warranty from Mercury. Yami gets 1-2 less GPH than my Opti. To me- not worth the extra $$$$

Re: help with motor selection
Timing and local certainly has a lot to do with price and selection, but this past spring, the local dealer gave me a price for a new 150 E-Tec (installed) that was 6K more than 2 local dealer's installed prices for a 2006, 140 4S Suzuki w/ a 6 year warranty.
