Yes, M200 is not dense enough for lag bolts.
Option B is too tight.

Re: LB26
Yes.
The mount bolts are too close to the transmission. Are you certain of those dimensions? If yes, I would certainly go for the L bracket. Imagine how difficult it will be to reach the bottom of the oil pan in case you need it. I suppose you have an oil change pump but still, I like better access there.

Re: LB26
First I do not have your boats plans and second I have never seen one like it so this is just general boat comments.
I have owned a few diesel inboard boats and been around a ton of them. All the glass boats have had the engine sitting between the stringers. I would want to through bolt the stringers with angle iron to support the engine. I would never trust lag bolts over time. That is not too heavy of engine so the mounting angle does not need to be real heavy.

Evening Guys
Well all was going well until today....
Glassed the hull inside, cut and first fitted the structural frames, removed them ready to to build the stringers and engine mounts.
Built a mock engine and then started to check engine angle and line etc so as to decide on stringer height.....
Then spent the next 4 hours checking every measurement from every angle and still can not work out what was wrong. Basically it looks like my shaft log is 100mm forward of what it should be. BUT I can not find the fault which is very frustrating all measurement, angles seem fine.
So the question I need advice on are as follows.
If the engine is 100mm forward will it affect balance.
The drawing shows about 200mm between the stuffing box and the coupling plate can I reduce this to 100mm. ( the supplier says that will not be a problem )
The thought of moving the shaft tube does not bear thinking about....
Cheers
Les

Re: LB26
Certainly a lot easier than threaded inserts as long as you locate engine stringers to allow for the angles. The m200 might need some overbores for the angle connections. Were you thinking the angle is bolted to the side and so the engine stringers are wider than the engine mounts?Fuzz wrote: ↑Sat Mar 19, 2022 2:00 pm First I do not have your boats plans and second I have never seen one like it so this is just general boat comments.
