"Hello folks, Been a member of

"Hello folks, Been a member of the forum for awhile but I hardly enter any questions since most of mine are being answered by other members already. However, I recently was looking through the SELOC manual (#1311 - Covers All V-Engines 65 Jet - 300 HP, V$, V6 and V8 Models)for my OceanPro 200 (Page 2-76/77) and noticed that the General Engine Specs for my engine (200), year (1998) were the same for the 185, 225 and 250. So my question is: whats the difference between the four engines? What makes the 1856 a 185 hp engine, a 200 a 200 hp engine vice a 225 or a 250? What am I missing? THe carburators maybe?

Can my 200 be converted into a 250?

Any insight in my curiosity will be appreciated.

THanks in advance,

Robert"
 
"Robert, most of the outboard

"Robert, most of the outboard mfg's will use the exact same powerhead for a series of motors.

So while the cubic inches is the same for say a 200 and a 225 the difference in almost all cases will be the carbs and quite possibly the exhaust. On some models the intake will be different or there may be a restricter plate. Still others will have slightly different timing.

So can motors be converted. Most times the answer is yes, however, the cost is usually prohibitive compared to the gain that you notice.

While it may sound like a big increase going from 200 to 250 horses, depending on the rig you have it hanging on it may only increase your top speed, in absolutely ideal conditions by 3 or 4 mph. Considering, at the very least you may have to replace 6 carbs to accomplish that (at a minimum of a couple hundred bucks a pop) how much do you want to pay for the extra speed? 300 bucks per mile per hour......"
 
"Graham,

Thanks for the exp

"Graham,

Thanks for the explanation. I was more curious than anything else.

I have the 200 on a 1998 Aquasport 225 Osprey Center Console. At WOT, she runs 33-34 MPH (GPS) at 5500 RPMS. Currently propped with a 15 inch aluminum prop with 16 pitch blades. I just put on a stainless steel remanufactured prop thats 15 1/2 in diameter with a 17 pitch blades that have been cupped. The prop shop told me that this prop should give me a few more MPH and would help me when off shore. I usually run 20-30 miles off shore to get to the fishing grounds in Central Florida.

I expect my RPMs to drop but hopefully not lugg the engine down. If so, the prop shop will rework the prop. I haven't been able to run it yet.

Again, thanks for the explanation.

"Robert, just off the top of m

"Robert, just off the top of my head, your new prop may drop your rpm's down to about 5200-5250 which would still be more than acceptable for that motor.

And while potentially you may see an extra 1 or 2 mph out of it, more importantly I think you will see a much improved "hole shot" and slightly better control particularly when turning at higher speeds. Additionally, you should be able to get on plane at a slower speed/rpm than you did before.

It sounds like the guy(s) at the shop have given you good advice and sold you a prop that should work well on your set-up..."
 
"Yes, I used Hall's Propel

"Yes, I used Hall's Propellers out in Christmas, Fl. Been recommended by many people. Does quality work and is quite reasonable wrt $$."
