I just bought a boat with an older 85hp Evinrude, early 80s I believe, and running on the muffs water looked to be flowing fine out the leg, but my understanding is that there is no tell tale or way to ensure cooling underway on these.
I've read the thread on installing a telltale but drilling into the block does concern my a little. Is there another way? Any way to install a temp property or something without drilling in? Would most of you even worry about it or just test it on the muffins each time first? Or every other time out? Just wondering if I'm worrying too much. Or should I just change out the impeller every other year and not worry?
Thanks.
