I called mack boring . millimeters, Thank You , another boater said 315 would be a good choice, I am on the fence with the 4lv 250...This is the drawing of 6LPA-STP at 315 HP. It is the same engine as 6LPA-DTE/DTP at 260 hp. The 287 mm distance ofengine mounts are shown. That measurement is from the engine center line, so you need to double the distance. Looks like 287 mm is equal to 11.3" each side.
It may depend on price and desired speed. You will need a larger shaft and everything that goes along with increased HP of the 315. I looked at the 4LV-250 3 years ago and it is surprisingly similar to the 4LHA line. The 4LHA line was very reliable. I owned the 240 for 12 years and a pair of 200 for 5 years. Never had a problem. That said, if you are looking at the LP- 315 is a good engine. I do not know the new versions, but the 6LP I know have a timing belt and 24 valve heads. More maintenance.I called mack boring . millimeters, Thank You , another boater said 315 would be a good choice, I am on the fence with the 4lv 250...
working on it , probably stay with 250, Thank youIt may depend on price and desired speed. You will need a larger shaft and everything that goes along with increased HP of the 315.

Compact motor! Can you tell us what your expecting as far as numbers? Going in the boat in the pic? What wheel, gear, rpms, anything to shed a little light is appreciated!I had the 315 on two of our company workboats. we ran the boats overweight regularly and they stood up well.
only related problems were carbonized turbos.
depending on the hull your are repowering the LV 250 may be the better fit.
our lv 250 is going in now

Thanks a million, really appreciate it! I’ve got a 41b in a 26’ Duffy. That yanmar sounds like it would be the perfect motor!Hi Tom,
Yes, the lv 250 is going into a 28 cape dory formerly with a tamd41a.
going with a 72c 1.9:1 3800 rpm 4 blade 18", pitch tbd.
Estimate 22-23 kt top end 14kt cruise.
Previous owner had upgraded and replaced a lot of components on the engine and was running well at takeout.
Our concern was the transmission (MS4a) which was mechanical and the weak spot IMO.
Speed is not the rationale for repower, reliability and ability for worry free cruising primary factors.
We looked at a number of engines including another volvo, the LV 250 was the best engine IMO in a number of respects
The extra horsepower and great torque curve will make it a different boat.
We're pretty psyched.
