Boat slow after cleaning

[cvtech1]

Hello I have a question, I had my boat cleaned and “waxed” which what was supposed to be done. After this I took it out the next day and could not get on plane with 4 people in boat which I always have until this so called cleaning. I’m running a 90 hp Yamaha. I notice water was pushing up on both sides toward the front, like it was dragging instead of gliding across the water. I had to be sure my trailer was not attached, it was pushing up like something was under the boat. So …. Mad. Could they have used the wrong stuff on my fiberglass hull?

Did they do the just a cleaning and waxing of the outside of the hull? Did it sit outside and take on a bunch of rainwater at wherever it was cleaned? Did they have it off the trailer to do the job? Have you done a complete visual of the bottom and the prop for possible damage? I am just thinking of a lot of possibilities.

No.unless the last coat was Rhino Liner.

Pull the plug or turn the bilge pump on.

Sounds like someone messed up and used NOTSOFAST on the bottom of the hull.

Easy to fix. Any hull cleaner will remove it. Once removed, apply two coats of IGOFAST. Problem solved.....lol

Doubt it has anything to do with the finish used. Check the motor trim (or trim tabs if you have). They probably threw something out of adjustment while applying finish to the transom.

Not sure of Yamaha, but most outboards adjust trim with an adjustable pin. If they removed the pin to finish the transom, they may have forgotten to put it back in, or put it in on the wrong adjust holes.

I agree with a copy of above posts, check the bilge for water.

Technically wax below the water line is going to be SLIGHTLY slower, but... Nothing you would ever notice on that boat. Based on your comment about it pushing water, check where the motor is trimmed at. If you had a bilge full of water, it would probably be riding bow high.

Did they clean the inside of the boat? Perhaps the flotation foam got saturated? This can add a lot of weight.

Impossible for the foam.to be saturated from cleaning the inside of the boat . Takes a long time for closed cell floatation to " absorb " water ,not going to happen overnight.

I seriously doubt it's a 'water-in-the-boat' issue. You would have to have a LOT of water slopping around to prevent a 90 horse outboard from planing the boat. That amount of water would be clearly noticeable.

Hopefully the OP will come back with an update.

Sorry for the long delay, I noticed it was a little sticky on the water line after I came back. I used some fiberglass cleaner and marine wax and it felt much smoother. I took it out the next day and was running 35mph but I was alone. A couple of you mentioned my trim on the motor and it did seem like it was not trimming up while under way. I stopped the boat and it was trimming up just fine. Could it be a trim issue under water pressure? Thanks for your replies.

Yes it could be an issue under power. Low fluid or leaking relief valve?

Normally if trim is causing planing issues you have to trim the prop in towards the transom.
Not up towards the sky.

Yes I realize that and I was going down to get it to plane and up to increase speed but no increase of speed but no increase of speed. Also no water in bilge the auto never came on and I did manual and still no water.

It went up fine when I took it back out alone and was running 35mph. Could having two grown men in boat cause the trim to be affected under way? It’s never been a problem until I had a rookie (car guy) clean my boat.

Lol.. nice!!

Perhaps it was just a coincidence that a possible loss of power happened at the same time as waxing the boat. It might be time to look at the motor. Compression check first and then fuel, electrical, etc. If you work at trouble shooting problems sooner or later you will find yourself chasing two unrelated gremlins.

In this case blaming the detailer is like blaming the Auto repair shop for your check engine light coming on and the car is running rough after you picked it up from having new tires put on.
