4 Stroke Weight Rephrased

[RidgeRunner]

I understand what you are asking.
Being that your bracket is a 24" setback the 478 pounds will carry better than the 30" setback. It will more than likely sit in the water just as my 20CC does with the 30" setback carrying a 200 carb at 389lbs plus the hydraulic steering where I have no issues at all. I guarantee I have one of the heaviest CC out there. (Especially with me in it:) It is not a self bailer either but it would still bail with the boat empty moored to the dock. Lots of weight was moved fore in my boat and the cap off restoration allowed for extra bracing of the transom which I suspect you already have being X-seadrive. Being that yours is a cuddy with more weight up front I would suspect it would be more forgiving than the CC with your proposed modifications.
My current set up is OK. Yours should be OK.
If you can give me until 9/14 and I can answer with confidence as to what happens when you add that much extra weight to a CC

Trim tabs always aid the operator under certain conditions but were not necessary on my boat. The main reason I hear for tabs is porpoising which is not apparent on my rig. I would not feel compelled to install them if I had it to do over.
Nice accessory.

There is no doubt in my mind that your cuddy would carry the extra weight of the four stroke and bracket. It will sit lower in the stern by an inch but no more than two inches. Isn't the 21v simply another foot of transom added to the original 20v?

If I were going 4-stroke I'd take a hard look at the Suzuki 150.

I would not go 4 stroke--I would go with a FI 2 stroke--Evinrude or Merc--E-Tec or Optimax--in a 150--weight is much less and the power much better--and fuel economy is a good as the four strokes with alot less maintence.

You are the man. He did just that. JOE purchased a 150 Optimax for $11,000 something. He is on vacation this week. Last week he installed the bracket. Next week the motor arrives. I am somewhat glad he didn't listen to me. I now feel 500 lbs is a bit too much weight for the bracket on one of these as you know what I have been up to.
Check out his thread on the bracket install and Bit the bullet on the motor.

I did not catch that in his other post--sounds like he made a great buy.

Ya--by the time you put that much weight 18" plus back it multiples fast what you mount back there.

My 200HO is probabley overkill on my V-20---But the testoserone flows freely when I am in the boat---LOL

Mercury is now making a 200 verado that is an inline 4 cyl. It weighs almost as much as a 200 optimax.

It weighs a bit more according to MERCURY, 497 for the large 3L 200 OPTI and 510 for the 4 cylinder VERADO. Also remember that MERCURY doesn't count anything else in the weight of the VERADO than the engine, midsection and lower unit. They strip them down to essentually only what is required to make them run and drain the oils out and use that weight number.
