I've read that volvo penta d4 engines have issues. Are they as reliable as the yanmars? My 2008 R25 had yanmar 110 and never gave me any problems.
In fact when my impeller broke a vane, the engine went into idle mode and got me back to my slip. Temp. went up to 220 but no damage. Didn't even realize it till the alarm went off.
I'm looking at a ranger tug 29 with a penta d4-260 and a 2015 31 with a d4-300.
