1995 Wellcraft 238CCF

[JDLC]

I have a 1995 Wellcraft 238CCF with a single 225hp Johnson Ocean runner that I would like to repower with a pair of Yamaha F150's. My mechanic told me that the transom cannot take pairs.

Has anyone with this same make/model repowered recently to pairs? If not possible what single OB recommendations would you have or is there a brackets that can fit to allow pairs.

My 225hp runs the boat at 25MPH at 4700RPM WOT.

HELP!!

Back in the late 90's I rode in one with twin 200hp Johnsons. It was fast as hell. It burned so much gas he had a leaving post made that contained another gas tank. The guy that owned it was pretty crazy, but he never sank the boat.

I would email Wellcraft and get their opinion!

There is something wrong with your setup and I mean bigtime wrong. I have a 218ccf of the same year with a 200 hp Yam on it. Mine runs 45 mph at 5800 rpm with a heavy load, and that is GPS. Do a compression test to see if the motor is worn out, then have the lower unit checked. If those check then check carbs and fuel. What pitch prop are you running. I am running a Yam black 17 pitch. My boat is rated for 300 hp so I dont see why the guy told you you cant run twins. I have been told I can run Suzuki twin 140 s with no problem. How is the condition of your transom. My boat is in mint condition and has been garage kept from day 1. Let me know if you want me look at anything on mine to compare.

wow dave, those are good numbers for that engine/prop. i had a '96 218ccf with a 200 ox66 with 17 pitch and ran low 30s/MAYBE low 40s unloaded. i just put a 250hp ox66 and it runs 49mph @ 5500rpm with 19 pitch now. I asked about twins, and I had a tech tell me there wasn't enough room. My capacity plate is missing, but this should solve all problems, just look for the max hp rating.

I am getting ready to repower my 238 CCF also. I have a yamaha 225 ox66 and at 4800 rpm I run ~ 25 knots.

Keep in mind that this hull is a much bigger and heavier boat than the 218 ccf!! The 238 is a 25'4" LOA and weights 3800 dry. Add in my 300 pound T-Top, 300 lbs of water (full live well), 1000 pounds of fuel, 800-1000 pounds of fishermen and another 300 pounds of tackle and yes, the 225 is struggling - especially out of the hole.

I have seen a few on the net rigged with twins 150 OMC or yamaha - but those were 2 strokes - twin F150's might be just too much weight for this boat. And a F225 as a replacement is likely to be slower on the hole shot ..maybe a single F250 or a Suzuki 300?

I'd even considered the HPDI 300 for a spell - until I saw that Yamaha no longer features them on their website.

I too would love to hear any thoughts on the optimal repower for this rig!

I went back to my 218's specs, and it's rated for 300hp @ the prop, so I guess twins would fit, don't see why you can't put twins on a 238ccf? my dry weight with a 200hp is approx 3700lbs (wellcraft specs). That's a big rig with only one engine.

Looks like twins were available from the factory...

Why don't you get the Boat Propped right before re-powering?Should be turnin' up about 5500 or so.Seems way over-propped.
