My personal preference, Makita 9237 hands down. I owned the 849X for about a year and it was a fine tool, but some of its quirks got a little old to me. I now have the 9237 for sale and own the PE-14. Some of the quirks with my dewalt were:
- It ran HOT. 4+ hour compound jobs with a wool pad made it difficult (if not impossible) to hold onto the body of the unit.
- On a startup, The RPMs would ramp past the dialed RPM and then slowly return. For instance, dial it to 1200, it would rev to, say 1500, and then return back to 1200. On trigger-finesse situations, this got a little annoying (to me)
- I found that the throttle was not as smooth as the Makitas- even a 10yr old 9227 had much smoother speed control and did not "jump" around its RPM range nearly as bad.
- LOUD. Without load, it is a fairly quiet machine, however, run it on speed 3-4 with a load and its downright loud. I'd say the Makita machine is significantly more quiet- maybe its the difference in "pitch". And the PE14, well its pleasant.
I will give dewalt points for ergonomics, as the rubberized head on the machine is very comfortable and slightly preferred over the Makita.
Both are great tools, and for boats all day long, I'd prefer the 9237c. Don't let the 10A motor of the Makita fool you- probably the most torquey full size rotary out there! If you can get your hands on both machines before purchase, that should narrow it down for you. Don't touch the PE14 or you will want one!
Just my two copper coins
