trim controls

[rdzat]

My boat has a quicksilver controler my question is it has a button for up and down to trim , what is the purpose of the trailer button located just below the trim buttons, I know it raises the motor but why not just use the trim up button, Since this is my first boat im still learning and have a lot of what may sound like stupid questions.

With the trailer button you are (supose to be able to) just push it (at the same time as the up button) and the engine automaticaly go to the top of the travel so you don't have to hold the up button. <br /><br />(note key words supose to)...

Re: trim controls

I'll throw in my 2 cents... On mine, the up/down rocker switch will only trim up to a safe cruising point and stop. The trailer button will allow the unit to tilt to the full up position, passing the rocker switch's previous "up" stop point. I'm assuming this dual switch setup prevents the drive from being tilted to a point of cavitation while cruising.<br /><br />Jim

Seattle Paramedic (no doubt a Mariner's fan) is right on the money with his description. On I/O units, the maximum trim limit switch not only prevents loss of performance due to excess trim...but more importantly prevents damage to the u-joint.<br /><br />Walt

Re: trim controls

Thanks Walt, I learned something here too.... What your saying then is that the joint is apparently not designed to operate at the full upright angle and would sustain damage?? Good to know, Thanks!<br /><br />Jim

SeattleParamedic:<br /><br />You are right on trailer control & Walt is correct also...<br /><br />There probably some people out there, like myself, that wish the "trailer" control would back trailer in water so loading would be much easier when by oneself!!! LOL<br /><br />

Re: trim controls

My ex-wife cost me many hundred of dollars on two separate occasions when she either attempted to park the truck after I unloaded the boat (I say she "attempted"...but instead dropped it into the river) or attempted backing the trailer down the ramp. Again, I say "attempted". She didn't quite make it...but did manage to literally t-bone crash it into a retaining wall with full crowd of late Sunday afternoon boaters watching. Busted every light to smithereens, bent the tongue to he11, and twisted all the back rollers.<br /><br />So, yes Fone_Man...wouldn't it be great if "trailer" meant fetching your rig...or parking it for that matter!!!<br /><br />Seattle Para... Only in an emergency should you ever run your engine with the outdrive trimmed up further than what the maximum trim limit switch will allow. The u-joints turn whenever the engine is running (on most MerCruisers), so you should always start your engine with the outdrive down. Have you ever heard a MerCruiser fire up with the outdrive all the way up? It sounds like she's about ready to grenade. That's because the u-joints are turning at an impossible angle. NOT GOOD!!!<br /><br />Walt

Re: trim controls

Thanks for that Walt.... Did not know that the u-joint(s) are turning when the engine is.... These boats are weird!! I gotta do some studying of the Mercruiser Alpha One outdrive manual that's for sure, cause I want to replace my pump impeller - not knowing what shape it is in (a 95 bought used by me last year).<br /><br />Jim
