I may have mentioned this before and am unsure whether later models of the D4 (and maybe D6 on the larger inboard cutwaters) are the same but it's worth mentioning again. Mine as the 2014 C28 w/ Volvo Penta D4.
The Low Speed button on the shifter is meant for only low speed operations (fishing or entering a harbor slow). As it was explained to me (in laymen's terms) it decreases the pressure on the transmission clutches and allows them to slip slightly. This is not a problem at the very slow speeds. However, if one forgets to shift out of low speed and travels at higher rpms it will cause the clutches to slip much more than they should which, in turn, will prematurely wear out the clutches. The fix is a transmission rebuilt.
One of the symptoms of this is a definite 'chugging' (as though the transmission is not fully engaging) when you're in low speed mode. I noticed it most on my C28 at about 2 knots. I purchased my boat 2nd hand and didn't have enough experience to check for this prior to buying. However, I must admit that I forgot on numerous occasions to shift out of low prior to traveling. It was an expensive lesson to learn. I now pay particular attention to ensure, when I'm done fishing, that I shift to the std mode. Given the severe consequences, I wish there had been some kind of built-in warning if one attempted to do otherwise.
