re-powering

Just a far flung guess but the Merc Diesel package will probably cost 12k-14k with outdrive. I know Merc sells the 120hp with drive for 9k. A diesel package in a SC is my wet dream. [img]/images/graemlins/wink.gif[/img]

Fr Frank, Scott and Brian, thanks for the replies. You have given me something to think about- especially the diesel option-with gas so high, it is food for thought. If I choose that route, do you think a Mercruiser diesel pkg would fit the existing transom cutout? Or is surgery required in your opinion? Again thanks for the feedback, Bob

These days diesel fuel is more expensive than gas by about ten percent.In fact in my area it's been more for the last three years. Thats at the service station. I'm not sure about marina prices. Diesel routine maintainence runs more also with generally twice the oil capacity and more expensive oil and fuel filters. Plus the greater initial cost. All that being said the increased torque, safety, and better range make it a tough choice. Another plus for the diesel is that a lot of it's increased initial cost may be recouped by an increase in resale when you sell. For me it would boil down to the amount of use. The more hours I put on in a season the more I'd vote for diesel.

Besides the Cummins-Mercruiser outfit check out the Volvo Penta and the GM offers.

Bob,

Only Mercury can tell you if a new motor/drive will fit without cutting. Diesel is $20c cheeper a gallon where I buy fuel.

The transom cut-out is the same. Engine mounts may have to be fabricated, though. Not a big deal. The current Mercruiser/Cummins or larger (240 hp & up) Mercruiser/Yanmar combo's are supposed to be "bolt in" replacements. (Just for the record, though, there really ain't no such thing.)
Volvo Penta has 16 different diesel sterndrives ranging from 130 to 350 hp, and ranging from $18.7K to $33.4K

Fr Frank (and all ClassicSC members): if one removes an I/O 165 HP in-line 6 cyl engine from a 23' SC, what would be a comparable replacement outboard engine, on a bracket? Thanks you for your comments, aaf

FELLOW-SHIP · #8 11-03-2005, 11:27 AM

I would go with either a single 225-250 two stroke with or without a bracket, or a 250 4 stroke, or twin 130 with a flotation bracket.

After much research, I just bought a 250 hp Suzuki 4 stroke for my 23' CC. It was a toss up between the Evinrude E-Tec and the Suzy, but the 6 year warranty on the Suzy made the difference. [img]/images/graemlins/smile.gif[/img] [img]/images/graemlins/laugh.gif[/img]

Comparable performance could be achieved with a 175 - 200 hp outboard on a bracket. But a better choice would be a 225 or 250 hp motor, as they will use slightly less fuel at the same speed, and you will put less strain on the motor at a given speed, as well. Nonetheless, a 200 is plenty.
If you're using a flotation bracket (highly reccomended), I'd consider one of the new 275hp '06 Verados. Scuttlebutt has Mecury releasing a 350 hp and possibly a 400 hp model by '08. I do know that Mercury is currently testing engines of 350 and 400 hp configurations. Look to see them in racing before they hit the consumer market.
Also, one of the boat rags I looked through in the grocery store had a bit on some guy out on Lake Powell who had altered his 300 Verado on the back of his 26' Sleekcraft to produce 485 hp. It pushed his 26' cuddy cabin boat to over 75 mph.
I wonder how long the engine lasted. [img]/images/graemlins/grin.gif[/img]
