When you say compress, do you mean flatten or just get a good all around fit for the seal between the two plates? Depending on your strength, hand tight for you may be tight as hell for someone else. Unfortunately, there really aren't torque specs or at least from what I remember, about how much was to be used for the oil coolers. Like you, I hand tighten the bolts as well. Sucks that any of us even has to deal with this.barely hand tight.. just enough to compress the seal..
I would replace them sooner rather than later.. the last time mine blew, it dumped half the oil in the engine in a matter of seconds all over the engine compartment.. it was then I said the hell with it and dropped the $$$ to buy the revised ones.. (2) engines at $12K each are not worth the risk in my opinion.Well there goes my plan, I thought that all of the units that cracked or warped had the bolt shear off. I guess the good news is that if I do have a failure it won't be catastrophic and I can keep a close eye on it maybe make it through the summer then replace the coolers in the off season. Thanks for the input.
I run my boat hard.. pulling tubes, wakeboarders, running WOT etc.. all summer.. if it was my boat after what I have experienced I would replace them before you have issues.. I know $1600 for 2 coolers is a lot of money but its cheaper than 2 $12K motors.
@zelone , I don't think anyone with a 2010 240 series boat is out of the build range. There is a clear difference in the oil cooler covers/faces of the 2010 1.8 l engines. The newer coolers have an arrow cast/embossed in them that points to the side of the third bolt down. Additionally the third bolt down has a different head than the other bolts. I will try and find the thread with pics of this or will take pics of my new oil coolers for you to compare with yours but not until after work today.
Nothing scientific here but the only change I made after I got the boat was to use full synthetic oil whereas the original owner usd standard yamalube. When my coolers were replaced the dealer used yamalube and I have stayed with it since. Did the synthetic oil contribute to my Problem? Don't know for sure but I think so and recommend that if you have older coolers stick with non synthetic oil. My engines are at 330 hours now without any issues since the oil coolers were replaced.[/QUOTE
Yeah, my starboard side cooler bolt broke either my second or third year with the boat. If you didn't purchase the YES, you were out of luck like me.
Between this issue and the warping towers that Yamaha will not stand behind either I think I am done with them.#Yamaha I know you fixed this in later years but perhaps you could issue something along the lines of a #TSB to your dealers?
https://jetboaters.net/threads/wake-tower-cross-beam-bending-ballooning.5119/@davel501, what issues with the warping towers? This is the first I'm hearing of this. What year boats and has anyone else had an issue with this?
