Boat riding weird after all day in the water

Re: Boat riding weird after all day in the water

They make an anode without the trim tab for the larger props, my boat came with out the tab.

They make a flat anode for that too.
The hose you asked about is the water intake hose.

Re: Boat riding weird after all day in the water

So I checked it in the daylight today. The prop seems to be fine and there's less play in the steering than I thought (only about 2 inches). I also notice a sticker on it saying it's a rebuilt unit.

Is it possible to upgrade/update the outdrive?

Re: Boat riding weird after all day in the water

My first thought would be to check the gimble bearing and or the universal joints on the drive shaft. It sounds like a binding isssue to me, especially with the noise associated.

Will do. Thanks!

Re: Boat riding weird after all day in the water

the annode was most likely removed to take the ss prop.

however, you might want to try one with a small fin. the tab on the fin helps counter the thrust deavation from the prop.

however i highly doubt this is the problem.

as jonsy said you may have water intrusion problems in the hull, i highly suggest you inspect your hull for any big chips or places where the water can get in. just because the water is not in the bilge doesent mean there is none getting in.

another way to check for a waterlogged hull is to weight the boat against factory specs. dont forget to take into account the fuel in the boat.
if you are 200 lbs over.....your wet

Re: Boat riding weird after all day in the water

What do you do about a problem like that? Just repair the fiberglass on the outer hull?

Re: Boat riding weird after all day in the water

When was the last time you had the outdrive serviced? Have you looked at the oil to make sure its not low,empty or full of water???

Re: Boat riding weird after all day in the water

THe hull might be waterlogged.

This gets my vote, but what do I know?
Annode? Seriously, people.

Uh.. Spun prop hub maybe?


The lil trim tab will help keep an even keel, but not that much...

Re: Boat riding weird after all day in the water

So it ran normally going out then as you described a few hours later. That is not a water logged boat. You would have to take on 1000lbs of water before you bogged that motor down like that. Think of it this way, one grown man is about 200lbs (some of us are much sexier than that), you put 5 people in there and you could pull a couple more on skies.

Have the motor checked. Make sure it is running on all 8. With the boat in neutral and the motor off, spin the prop, does it spin freely. If it binds, have the mechanic pull the prop and check it out.

Try putting 5 grown men, or 2 55 gallon drums in the stern of a 19' boat (on top of everything else you have in there) and see how well it planes out.

Re: Boat riding weird after all day in the water

The trim tab always helps if it's in the water. On some setups we run with that part of the LU out of the water, with the prop either near the surface, or even piercing the surface. In that case, a trim tab is useless, and we just use a flat anode. Often the skeg will be modified with a slight hook in trailing edge (torque tamer) to compensate the steering.

I'd bet the missing and thus mis-adjusted trim tab is most of your problem.

hope it helps

Re: Boat riding weird after all day in the water

I've had 1,100 pounds (7 grown people) in there for 7+ hours on the water and it has always been fine. There was no noticable change in the way the boat sat on the water. My swim platform was at the same level as when we left earlier in the day.

I'll probably just bring it in and have it all looked over. I live right near Lake Michigan and there are numerous Marinas and Boat service shops near me. I'll just have to put off the mods to my truck for a bit longer. lol

And guys, I was just asking to see if there was anything obvious that I could quickly fix myself. It sucks but it's not a huge deal. Please don't get into arguments over a silly thread.

Again, thanks for all the responses. The more I read the more I learn and I'm grateful for that.

Re: Boat riding weird after all day in the water

If the boat was sitting at the same waterline, then it's not a leaking hull.

Re: Boat riding weird after all day in the water

I have seen three or four posts on here that says that his boat would not get up on plane, but in his original post he never mentions that his boat wouldn't get up on plane...

It gets on plane but runs hard as hell and won't balance out.

I don't think this is a weight issue. Just that his engine was working harder and not holding a straight line like it was on the way out...

The engine is in a fixed position, it's mounted in such a way that it can't do anything but hold a straight line.

The OP said:
"tried to get on plane" still think it's water in the hull, the water was g-forced to the stern

"listing" still think it's water in the hull, trim tab or weight distribution improperly allowed the water to slosh to one side

"swim step was still level" still think it was water in the hull, the boat will maintain "level" until the stern takes more than the bow and sinks the *** end

"It gets on plane but runs hard as hell and won't balance out" water in the *** end

"It also looked like I was trimmed up too high by the looks of the wake, but I was all the way down"

Did it look like a wakebaord boat that had the ballasts full of water???

I wonder why? If you don't have factory ballast tanks, you now have some created by a leak, and all that water is between the deck, and the hull.

Next time out, you should notice that when you put in, the boat will plane out nice and quickly. As the day progresses, it gets sluggish, and you have what you are experiencing. When it does this, back off the throttle and idle in gear. Gradually, and very gradually bring up the throttle. You will plane out, because you did not g-force all the water to the transom, sky the bow and keep the water trapped in the stern.

When you first put in, use a little marker to mark the water line. At the end of the day, see how much lower it is.

Re: Boat riding weird after all day in the water

It's already scheduled to go in so I'll let the professionals take a gander. I don't have the know how or tools currently to tackle this and have it ready by labor day weekend.

Thanks everyone!

Re: Boat riding weird after all day in the water

UPDATE!

Okay, so my stern drive was in tip top shape. They drained and refilled with oil and lake tested it. They said it listed slightly but nothing out of the norm.

Well I took her out yesterday. As soon as I got on plane, listing to the port pretty bad. Slowed down and got off plane, then tried again. Same result. Well, we figured we'd just putt along to the channel to the big lake. Then my wife said to me, why not just try it again.

HOLY CRAP, she planed up and ran perfect! I had and still have no explanation. We were in the water for a little over 2 hours and it didn't list at all the rest of the time.

So now I'm completely confused and think it just may be a funny weight thing. I ran into another boater at the ramp who had the same model boat and he told me they're rather picky about weight distribution. He's owned his since it was new 1986.

I think this throws out the waterlogged hull ideas, but I'm still going to have somebody look that over.
