[dexman38]

At the dam run i took the boat out about a hour before and ran a 62.4 gps going up river . picked up a mel and a two of his freinds and could not get the boat over 50. I ordered the scan tool for the 496 ho since i can not get my boat in to a shop before the end of the month. no fault codes where thrown. everything appears to e o.k. but i lost 10 mph. all so i pulled the prop off and that black plastic sleeve had a hair line crack . could this be the problem. HELP. :eek: :confused:

I knew something like this would be said.. :rolleyes:

[mike37]

I don't think he was dragging him from a rope underneath the boat. :D
you sure about that

[dexman38]

O.K . Lets get back to the real problem. do you think that prop sleeve is the problem.

[mike37]

OK on a serious not
the last time my boat started running bad I changed the plugs
and it ran like new
I think its time for me to do that again we ran week at the dam run

I would replace it but if you didn't notice any vibration that probably not it

[dexman38]

scan tool said i have 84 hours on the motor

[dexman38]

i am going to change the plugs and oil this week.

[mike37]

scan tool said i have 84 hours on the motor
that about the time we did the plug change
we are at 150hrs now
also check and see if the belt particles are getting in the spark arrestor
we had that happen if the belt isn't tight

[Kilrtoy]

You packed another 700 pounds on the boat....
wow.....

[mike37]

wher did you get the scan tool

[Essexive G's]

Next time you pick Mel up, make sure he leaves all his booze bottles on shore. Then you should only lose 2-3 mph.

We are talking about the prop hub, right ??

[dexman38]

right the prop hub

[INSman]

I would order it from Teague Custom Marine in Valencia

[dexman38]

i will drive there tommorow and pick one up thanks. it looks like i will be working on the boat tis weekend.

[franky]

then when you hit something you take a bigger chance of taking out something in the outdrive also. keep that in mindif you have the plastic hub just check it every now and then, if it looks cracked/damaged replace it. I am assuming you have a fairly stock type boat.
also I was told by someone who has done the test/calculations that for each 28 pounds of added weight, you need 12 more horsepower to maintain speed, that would be 300 more HP.
opinions, rumor and my 0.02

There is a fairly well known problem with some of the 2003 and 2004 Bravo drives, hooked up to Merc 496's that you should also be aware of.
Prior to selling my 2004 DANA, I took the boat in for a 50 hr. service, just so the buyer was starting fresh. Long story short, Merc picked up the tab for repairs to the drive resulting from leaky bellows that caused u-joint rust and such, to the tune of $1,300. This was while the motor and drive were past the 1 year warranty period.
For precautionary measures if not already done so, I would have the 100 hr. service done and make sure they pull the drive.

Gettin mine looked at... :wink:

Look at the added weight and the engine compartment temp! Mercs run FAT, that is how they give you the 1 year warranty. If you had temps, over 175 degrees (F) in the motor box, the motor would run FAT. Your motor will always run better in the cool of the morning, and 'drag it's ass' in the late afternoon heat.

[desertbird]

I never paid much attention to the difference, but UP River with a pitot, you'd read faster, since you were going against the current. DOWN river you'd read slower.
Traveling on a moving body of water....like airspeed vs. groundspeed. Does that make any sense? :confused:

They also run a closed cooling system and a thermostat.So pretty sure it wasn't running hot.Not to mention the water in Mojave is cold! ;)I'd go with the added weight those are some big boys!

not brass/// it' s a solid hub, never use a plastic hub on a big block ;)
