HELP

Sorry. Im trimming the outdrive up and down... when its all the way down it seems fine......Like I said in my bass boat with the outboard. It went faster when I trimmed it up.. this one seems to work the opposite...

Thanks
Terry

If you have a speed-o-meter this is how I adjust that.

Once your on plane with the drive all the way down tap it up a few times until you see your MPH go up without adjusting the throttle. When you see this your at the sweet spot. Anything farther up will just slow you down. It's a very slight adjustment so just tap it a few times till you see it adjust.

Trim tabs as cr0ck1 are mostly made for leveling off the boat and at cruising speed and can help with getting on plane specially the bigger boats. I'm gonna guess you don't have trim tabs on your boat.
 
no.. and I actually have to replace the speedometer.. the cable is broke in the back and I think a pice is missing.. so I am jsut going by my ear... hope to have it all running good by the end of summer..


Thanks

Also, any further "UP" and you begin porpoising, and prop cavitation.
That's the sounds you heard when you described it as:

"it seemed to sound like the motor was out of the water"

It is not a good thing, and you don't want to run her at that pitch.
 
The primary difference in trimming between the outboard and the indrive is probably due to the Deep V hull. The bass boat is designed to fly across the water with very little touching the water. The Sea Ray hull is designed to handle chop and waves, so you won't see the speed increase from slight trim adjustments like you did on the bass boat.
 
A couple of comments on the last several messages here.
Good luck on getting a manual. I doubt there was ever anything created like a manual. The sales brochure is about all you will get. Most manuals won't tell you the answers to these questions anyway.
Just to confirm, you are pushing only 1 button to raise your outdrive, right?
Some boats can not tolerate much raise of the outdrive. Some, like mine, don't need it - and I almost always keep mine down. These older boats don't have the bigger, flatter planing surfaces at the rear like the newer boats do.
Unusual advice to raise the outdrive in rougher seas. Most advice is to lower it, so that the bow can cut through the waves instead of letting them pound on the bottom. Again, your older design probably has a finer bow that will cut through better. Newer models have more bulbous bows to make more room inside, but they don't cut the waves as well. Of course, they pound more on the bottom too. Raising the outdrive and the bow may work in a small chop if the boat can remain relatively level, but in anything larger (like 1 to 2 ft swells) the boat will pound terribly with the bow up.

This old 120 may not have enough power in this boat, which is probably a deeper V than your bass boat, to really get it moving. If you can't get the boat moving fast enough, raising the outdrive will have the opposite effect - like doing it as slow speed. Tune the engine as best you can, then work with your propeller to get the best performance possible. You may want to give up some top end to get more power at lower ranges. Then you may be able to trim up a little.
 
thanks for the replies... Dont get me wrong it has lots of speed now.. I was jsut concerned becauase I thought I was supposed to be raising the prop like I did the bass boat.. SO I guess Im good leaving it down like I have been.. I jsut didnt want to do anything wrong. Now jsut gotta figure out what the other button is for..Ill take a picture of it and post it here


Thanks
Terry

Hey guys. got the boat running good.. Took it out last SUnday and Had my girlfriend drive it and I ended up needing to adjust the timing more.. and after it warmed up it ran great... Would still love to get manual for the boat though.. Some things on there I dont understand., Like for example on my bass boat that had an outboard Mercury Black Max 150hp. To get the boat to plane out I had to get it to a certain speed and then adjust the trim.. and it jsut kinda skimmed on top of the water... Well with this boat as long as I leave the trim all the way down I get alot of speed but when i try to raise it doesnt do what the other boat did.. Now Im new to this so maybe Im not supposed to do that or im doing something wrong.. Now on my trim control.. there is an In and Out button.. that raises and lowers the trim... then right above that there is a button that jsut says UP... it doesnt seem to do anything... Anyone got any ideas??

Thanks Again

trim all the way down will make you go slower (not exactly but it will make the bow lower).. the higher you raise the trim the higher the bow will rise.. i cruse around mid trim.. if big waves come and i want to get over them without the boat jumping up and down i adjust up so im cuting through the top of the wave instead of bashing thorugh it with the bow..

You are cruising around mid-trim? :smt017 I would think that would be too far...I usually tab it a couple of times which is just over 3/4's down (or a little under 1/4 up).

:smt017 you trim up more because you are in rougher water :smt017 That is a new one for me, now granted I boat on lakes but when the lake is rough I would usually trim all the way down not mid-up :smt017 But you know more about how your boat reacts to the gulf than I do; but the person asking the question lives in Ohio :smt017

ok :smt017 why would i trim down if there are 2-3 ft seas.. i want to cut over the waves not smash the bow into them. if i try to haul a** with the trim all the way down i will just have a bumpy ride and get wet.
 
Crock - I am not saying you are wrong, just that was a new one for me. Again I do not boat in 2 to 3 foot seas so really have no idea, just sounded unusual because I would think the water would be breaking on the bottom of the boat instead of the bow. Again you know your water better than me, I just did not see where the guy had a problem with how the boat was reacting in large seas yet trying to figure out how he should be handling the trim for optimal performance.


Terry - sorry to get off topic - have you tried to operate the switches while out of the water so you can see exactly what is happening when you hit the buttons? You say there is an in / out button and there is a button beside that says up but does not seem to do anything. I just wonder (and this just a guess) by what you are saying if when you hit that button your trim is going all the way down and all the way up. If you do this out of the water you will be able to see exactly what is going on down there. When you are doing this in the water you are only wanting the drive to move a little while hitting the trim up button.

Good luck with it.

na its cool man! dont mind me i just got off of a 13 hour day at work and im tired and cranky like a baby.. lol.. yea man.. on the gulf i gota have the trip half way to have a smooth ride.. unless its cam waters. :thumbsup:
 
A '74 probably has the low pressure trim/tilt system which is not designed to be trimmed up while it's in gear. There should be a switch to limit it's use to while it's in neutral.
 
The mysterious "UP" button lifts the outdrive the final distance for trailering. The normal "Up/Down" button pair are for trimming out in the water.

Not sure how the two stage hydraulics work. The 260 SD we just got has this feature. The others don't.
 
Thanks Guys.. I can lift and lower the outdrive with the up and down.. have tried the UP button while out of the water.. I will this week though.. No biggie, jsut new to this boat and I dont want to be doing or not doing something that I shoudlnt be... You guys here are great

Thanks
Terry
 
Also, to find the sweet spot you can play with the trim and if you don't have power steering you'll feel it in the wheel when you get it just right. The wheel will get real loose and not have as much pull or drag.
 
sealerman,
SeaRay has a archives section and they have been adding brochures for the older boats. They don't have anything for 1974 so I went back to 1972. You could also go look at 1976. Boats didn't change much back then though.
Click here for the brochure page for the 1972 180 SRV

Click here for the list of brochure pages for 1972

Click here for the full 1972 brochure

Check back there as they have been adding more boats over time.

One nice thing about those old motors is that they are easier to work on than the new ones. I don't think you didn't mentioned changing tho oil so I would recommend you do that so you don't use bad oil (dirty). With regard to trim/tilt. I thought most older boats had seperate switches. One for trim, which is the up/down range when driving the boat. One for trailer, which is to move the outdrive to the highest point for trailering.

We are waiting on those pictures. What color is the boat?

Hi.. finally got some pictures of my boat on Sunday. Again thanks everyone for your help. we have been having alot of fun on it...It wont let me uplaod any larger file
