Re: Stuck hydraulic for assisted tilt in 40hp

Thanks for the conceptual breakdown, and the practical bypass. Since we haven’t interacted much, basically when I decide to cut my teeth on a new family of motors, or a new generation, I usually pick up one that is a junker or needs a lot of love, and then a half dozen or more of them to get experience on after that one. Today was my first time seeing one in person, and in my own posession, and seeing the fuel, oil, and pressure in lines (from the crankcase) made me surmise from a conceptual point what you clearly explained. My question(s) would have been how the thing worked from a conceptual standpoint (which you explained really easily!!!!) and how the VRO ties into the alarm system, how I would disable/remove/disconnect that for obvious reasons (which you also answered, thanks again).

I mean, it’s a pretty clever piece of engineering several things together, but the risk of it failing and the potential catastrophic effects, all just to eliminate having to mix oil into gas doesn’t appeal to me. Although I can imagine the issue of customers just plain forgetting to mix oil into gas might have been the big reason behind this engineering addition. Either A), the customer is plain ignorant, or B) the friend borrowing the customer’s boat/motor is ignorant and ran it with straight gas.

My only other question about the VRO is how does that positively affect performance of the motor and/or improve longevity. This is one of my concerns on my 2014 Etec. Obviously that motor is direct-injected…everything….but what happens when the oil injection fails? I’m guessing the computer senses this and kills the motor off (it did when my 2-month old impeller decided to implode shortly after purchasing the motor for 6 large), but at WOT/5500 RPM, metal on metal is still bad combined with heat.

If I screw up the first one, I have basically nothing into it and I learn a ton. You guys basically save folks like myself a lot of time fumbling around to come up with a conclusion similar to yours, so thanks again for your willingness to share your knowledge and experience.

I picked up 2 of these yesterday (the ’93 40hp, and an ’86 50hp that has quite the story behind it…let’s just say 4 people almost died using it), and will be picking up a 3rd tomorrow (’81) which will hopefully be my main workhorse once I’m done going through the whole thing.

I have to ask, since I just went through (and still am to a certain level) the learning curve with the 25-30-35hp family…does this family of motors have any cooling system issues I should know about? From a very early observation standpoint, it seems like the same motor was made from the early 70’s right up through the mid-2000’s, albeit several revisions and enhancements. But they all look pretty similar. Would fit the build of the same progression the 25-30-35’s followed.
