I just purchased a 2003 295 CONQUEST.

I am continually finding water in the storage area under the cabin seats. I can find no leaks, water trails or rust marks. I keep the air running on this boat almost continualy at the dock and on the water. Could this be condensation?

This boat runs great once on plane but seems to get up very slowly. Is this other people's experience? Top end in moderate seas is around 32-MPH. It is outfitted with two four-stroke Mercury 225-HP motors.

I recently took the boat from Key West to Bimini. On the way back we hit six-foot seas with a few eight footers thrown end. Tough ride through the Gulf Stream but the boat stayed amazingly dry.

Four-stroke motors strokes are not going to get you on a plane as fast as a pair of two-stroke motors.

What props did you have on your Conquest with four-stroke motors? With two-stroke motors?

Check to see if the calking is cracked in the bulkhead where the windlass line is stored.
That was one of the source's that was leaking on mine.
Post here about the result's. We had many leaks in our Conquest.

Only 32 MPH with 2 Merc 225's ?
Our 295 has 2 225 Evinrude Ficht's and tops out at 42+ MPH on the GPS.

The performance sheet on the Conquest 305 with F225 states that the top end on that hull is 43 mph. I would think the performance on the 295 should be similiar. The hull designs are a little different.

Cheers ......

Thanks for all the responses. I will chek out the anchor locker and see if this is the problem.

As to the boat's performance I took the boat to the dealer where he he replaced the plugs. According to him after extended running of the motors at relatively high constant rpms as I did on a recent 175 mile trek the plugs burn up. Has anyone else experienced this?

The performance data on the whaler website for the Conquest 275 shows a 46.3 mph top end with a pair of 4 strok 225s and a time to plane of 4.7 seconds.

I wonder what it is for the 29.5 as this is a heavier boat and of corse 2+ feet longer.

Isn't the 295 Conquest a renamed 28 Conquest? Sounds like those Mercaha 225's aren't running right.

The 295 Conquest has a notched hull. The hull ends about two feet before the motors. A hull with this design is slower to plane because the weight of the boat is supported by less hull and the speed that the hull will hold a plane is higher than if the hull ran the length of the boat. Check into weight you have loaded on the boat. Is it overloaded? I find every extra ounce I have on my 305 Conquest effects the fuel economy and performance. With generator and air, I have a heavy boat.
My top end is 32 nautical miles per hour with bottom paint and the normal assortment of junk on board. Time to get on plane seems about the same as my 23 Conquest with a 225 single. That performance is acceptable to me as I want a fishing cruising boat not a performance boat.
The 305 has a full length hull and will hold a plane at very low speed.
I have YamaMerc 225 4 strokes and just replaced the plugs at 350 hours and the tips were just starting to wear. According to the mechanic, they would have been fine for another 100 hours. I would take what the dealer said about plugs with a huge grain of salt. Compaired to my old Optimax, The YamaMercs are great on plugs and running continuously at any rpm other than wot shouldn't cause the plugs to wear out.

I have a 28 conquest and I have the same problem (leaking). There was no water in the galley and after pulling it out at a moderate incline, there was about 3 gallons on the floor. Cannot figure it out. I know it holds a little water in the mid-berth but I would not think 3 gallons. Also pulling it out with the incline, it would make sense that the water came from somewhere in the front???

My boat is slow to plain with 17 pitch 4 blade props on yamaha 250's. I think the whalers are just heavy! I cruse at about 28kts pushing 4400 rpm's.

What year 285? Sounds slow for Yam 250's, OX66 or F250's??

I was cleaning the head on my 28 Outrage this weekend and noticed water appearing on the teak and holly sole. On my boat the AC condensate line dumps into the sump in the head. The pump works fine so no issues there but when I dump enough water in the shower/head to overflow the caulking joint I started to get seepage. This boat is in its ninth season and I believe the caulking has started to pull away slightly. I have had issues with water before. Once was a fracture in the freshwater line going forward. But the bulk, I believe, was from the head and I since replaced the pump and have remained dry. I will have the caulking stripped out and replaced over the winter.

I too had some major issues with water in the cabin (still have some minor ones). One major factor in mine was the anchor storage locker in front of the forward bulk head. Open your anchor locker, pull out all of the ropes and check the seam along the bottom area of the front bulkhead. Mine had about a 1/2 inch wide gap that the water just flowed through if I took a big wave or was in heavy rain.

The gap was actually so wide, that I couldnt just caulk it. I had to cut pieces of teak to fit along the bottom of the bulkhead and expoxied them in.
