1996 225 EFI...more help with take off problems...EUROPEANAM...

hey EuropeanAM...
as before you know i really appreciate your help and everyone else's so any info is appreciated this time as well...
Still having trouble getting my motor to get on plane...Just put a 26 fury on there, and can't hardly get it on plane even with the trim tabs down...But after the nose drops, she will FLY....at WOT, i can turn my 26 FURY 5700-5800 82 GPS...LOVING IT...(2003 Gambler OUTLAW)...
BUT...
#1 noticed my oil reservoir on the motor with LOW oil level
#2 with less than 1/3 tank of gas, still having to prime bulb after every time i've cut engine off(just rebuilt diaphram as you told me)
so...took cowl off after we got back from lake, and took a look AGAIN...noticed another one of the little oil lines leading to a cylinder to have POPPED off AGAIN, reglued it back on...then WOW, noticed the main oil pressure hose 5/16" coming from BOTTOM STARBOARD side to be SPLIT nearly half in two...fixed that and haven't had a chance to get back in the water....
ANY SUGGESTIONS before i go back???
COUld this have fixed my horrible take off problem???

It more than likely solved your LOW OIL LEVEL PROBLEM. You will however need to bleed the air from the engine mounted oil tank:

If you have not already done so, I would recommend that you perform a SPARK TEST on all six cylinders.

Additionaly, take a look at this post- and verify that you've upgraded fuel lines/primer bulb EXACTLY as noted:

http://www.bbcboards.net/zerot...first

fuel line was replaced back in january from tank to motor with one from walmart that says universal...it says on the package that it WILL tolerate todays gas standards...

SPARK TEST?...is there a link you can give me for that? i'm sure i can do that myself...

ALSO, everytime we go to adjust my TPS, it reads backwards....when the hotfoot is relaxed it reads like 3.80, when WOT it reads .95....????
do you think i should just go ahead and buy a new one? IF the motor didn't idle so well and RUN so well on MIDDLE and TOP end, i'd better worried, but she is strong in those ranges...

Fuel line: Replace it! Don't buy parts for your outboard motor at department stores.... unless they're OEM. I could FILL a 55 gallon trash can every year with "brand new- and totally useless" fuel lines of similar origin. http://www.bassboatcentral.com/smileys/wink.gif

Spark test: Attach a timing light to each plug wire, ONE AT A TIME. Watch for the light to flash. BTW... make sure you're running ONLY Champion QL77CC plugs. http://www.bassboatcentral.com/smileys/thumbsup2.gif

TPS: You better double check your testing technique against the directions in the service manual. You should NOT be reading 3.80V at idle.... this would INDEED be backwards (and would result in a very RICH idle, and a VERY LEAN WOT). http://xs-s.com/zf/images/smile/emthdown.gif

hey European AM...
replaced fuel line yesterday and all new Spark plugs....
Fuel line, definately fixed my starving problem...
the plugs i took out "were" the correct ones, but they were all REALLY REALLY RICH looking...could this be a sign that my TPS really is putting out incorrectly as i had reported when we checked it last time...
Remember i had told you that when we checked it, it read 3.80 at IDLE and .95 at WOT...
TOOK boat to the water and still couldn't get the boat on plane without sending partner to the front AND running down the trim tabs, but once the nose starting dropping, it will set you back and FLY...turned my 26 FURY 5800 at 82.3 GPS yesterday...
what NOW for the sluggish low end???

Let's go back to the TPS situation FIRST. We need to determine "exactly" how you are taking these readings before proceeding (the APPROPRIATE method is to utilize a TPS TEST HARNESS, which plugs in between the TPS and the engine harness).

The factory service manual has very good instructions for this proceedure.

If you have access to a DDT (or the Computer Diagnostic System), you could "view" the TPS voltage to confirm that the readings are "similar" (if they're opposite of your testing results- you're doing something wrong). http://www.bassboatcentral.com/smileys/wink.gif

well we dont have the tool needed, so i took it to a local outboard mechanic that does...
BUT
we were veiwing the voltage by unhooking the plug, and reconnecting it with 3 dummy wires that allowed us to put the end of the voltometer into the "now open" plug...

Between "which two color wires" were you taking your readings?

we unplugged, took 3 identical pieces of wire about 2 inches long, put slide on connectors on one end of each piece of wire, connected the connector to each of the prongs inside male end of plug, slid other end of wire directly into female end...This allowed us room to connect the black tester lead to the ground and connect the red lead to either of the remaining wires...i can't remember which of the wires in the plug gave us the numbers, but only one way would.
After we got the backwards reading, we figured we had it backwards and tried on the other wire and got nothing...

I will once again allow the use of my TPS harness if needed. Let me know and as soon as Rod Hipsher is done with it, I will have him send it to you. It would make it alot easier for Don to help if he got accurate readings from trusted OEM equipment. Let me know if I can help out, Jason Bubier http://www.bassboatcentral.com/smileys/USA1.gif

That's a GREAT offer- and an EXCELLENT IDEA.

Once you're set up with the harness- let me know and we'll go from there! http://www.bassboatcentral.com/smileys/thumbsup2.gif

well i really appreciate it, but i've already taken the boat to a NEW local guy that's been working on outboards for 20 years and HAS a Diagnostic Computer...
He called me this morning and after going through everything he knew, here's what he came up with...
#1 we WERE reading backwards somehow, and the TPS was just a LITTLE off on the idle end (1.08) WOT was (3.81)...
#2 he said the rebuild that my Dad did looked REALLY GOOD and compression checked out perfect...
#3 he did a few other adjustments that were minor...

Ultimately he said he didn't see anything that was WRONG or OFF enough that should be keeping me from running normally...
I've replaced spark plugs...
I've replaced fuel line with OEM mercury line...
this motor didn't do this on my Gambler 209...
I'm using the same Jack plate (bob's 10" hydraulic)

A couple more "pieces of the puzzle" may be helpful:

-What is your fuel pressure AT IDLE and AT WOT?

-What boat is this engine on now? 2003 Gambler Outlaw?

-What prop are you running? Still the 26 Fury?

-RPM's and WATER PRESSURE @ WOT?

Jason I am back. Let me know I will send it wherever you want. http://www.bassboatcentral.com/smileys/thumbsup2.gif
Thanks a lot ! http://www.bassboatcentral.com/boardstuff2/beers.gif

need to check the fuel pressure...
yes 03 OUTLAW now....w/ 10" bobs hydralic
26 fury, but have also tried my 25 trophy which does a little bit better, but i'm turning it over 6,000 on top end...
can turn the 26 fury 5750 at 82.3 GPS...
turn the 25 Trophy 6,000 for a short period at 80(+/-)

How many RPMs do you hit before it comes up on plane?

Rpm's can very to get on plane based on boat setup. I wouldnt think much could be diagnosed based on that. If he is having to get up front to plane out I am wondering if it is a set up problem ? I knocked off a plug wire 1 time with my cowl when i was putting it back on and caused this symptom. I know my tempest is very sluggish out of the hole but my trophy can keep the r's and jump right up.

thats the problem i cant get over about 2400 rpms....if i start swirving the wheel and let it start breaking away, all of a sudden it will RRRRR and start to cavitate if i dont ease out of it....

I did notice the other day that unlike on my previous boat, this one will do better if i leave the Jackplate on about 5 start dropping to 3 while trying to get up...seems that speeds the RRRRev up....and wont cavitate once she ever starts going...

did u ever try different pvs plugs ? cant even get my boat up with them small ones in even the mid sized ones are a bit small for my tempest but like u said soon at she lays down she is gone http://www.bassboatcentral.com/smileys/thumbsup2.gif

no the trophy 25 isn't a plus, so it doesn't accept any plugs...
the trophy 27 was, but only had 3 plugs to use...
the fury i've got, runs best on mid to top end, but doesn't have any plugs in, and i still can't get it out of whole smoothtly...
