Yanmar 110hp power

[Charlie]

Hi All
I am curious as to know what others think,Is the 110hp Yanmar underpowered for a loaded 25'. Am in the market for a Ranger 25" I have always been of the school that more is better when it comes to hp. But as I get older I find that going fast is not near as important as it once was. I understand that "fast" is reletive and that Ranger tugs or the C-Dory I now own are not considered fast boats by any means. Also what is the speed of a loaded 25 in good water in MPH with a 110. Thank you all hope to join you soon Love the Ranger seris tugs.

Hi Charlie,
I transitioned from a C-Dory 22 to a R-27. Fully loaded I can get about 18 knots or 20.7 MPH. I will tell you though I usually travel between 8 to 12 knots. At this range I burn between 3 to 5 GPH. At WOT I burn around 9 GPH. The comfort level from the C-Dory to the R-27 is light years and well worth the loss of MPH. Look at it this way, you spend more time gettng there in comfort.

The 110 serves us very well for our style of boating in our R25. Great economy and sufficient power to do what we want. Maximum speed for us is just over 10 knots at around 3200 RPM. Cruising at 6.5 to 7 knots at around 1900 rpm.

I also had the C-Dory 22 Cruiser and then transitioned to R25 with w/ 110 Yanmar. I think the advantages/disadvantages of the 110 will be based on your use of the boat. What are you planning to use the boat for? When I had the C-Dory I did a lot of extended fishing trips with occasional short week-long cruises. I needed the 20-25 knots to get out and back to fishing sites. I don't think the 110 will be enough if that is a serious interest for you. If you're more interested in crusing and will load up for 3-4 week trips to distant locations with a dingy, kicker, full water tank, full fuel tank, food stocks, spare parts, tools, oil/ lubricants, stern/backup anchor, traps/lines, etc can you accept/enjoy a 5-6 knot pace with top end of 9-10 knots (currents permitting)? Two other considerations -- I've heard folks say they like to have the speed to run ahead of foul weather which is a good thing. Unfortunately, despite monitoring the weather channels and reading the weather buoy reports via 4G, we've unexpectedly run into 3-6 ft seas on a number of occasions and couldn't have done anything with the extra speed. Finally, I have enjoyed comparing fuel consumption with some of my crusing buddies but they usually get to the anchorage quicker than us.

I have a R25 with a 125HP Yanmar. Fully loaded for a 2-3 week trip including generator, dingy, outboard, BBQ and just about everything else we usually cruise at 11-12 knots at 3200 RPM. This will get us around 2.5-3.5 gph, depending on currents, wind, tide, etc. So the numbers mentioned above for a 110 HP Yanmar seem about right. Since the Yanmar's have a lot of torque we have been pretty amazed when we don't really slow down when the waves pick up.
