Diesel inboard vs 4 strokes

[dginge]

I have a Yanmar 6LP on my sceptre with a bravo 3 drive. I love the ride. I also agree on the sound. It starts immediately and purrs like a kitten. I grew up on a twin sceptre and they ride totally different. The IO with the enclosed transom rides deeper and the weight of the twin OB always seemed heavy in the rear (bc it is). If you put twins on one they better be on a floating bracket. I wouldn’t give my boat up for another boat and it’s a nick nackers dream. Always something to tinker with. I could literally tinker for days. 8-5pm!! Ha. Check a zinc here, tighten a belt here. spray it down with corossionx and stay on the maintenance. Paint on a Yanmar sucks real bad and they like to corrode. Keep ospho around and a primer and paint and it will last a long time. Mine has 388 hours on it, cruises 32 mph at 3150 rpms with a max rpm at 3800. It will touch 43 mph trimmed out nicely. I get 3.8 mpg at cruise. Very efficient and not noisy. Buy the onboard!!!!

Maybe the type of use is also a factor......
Example.......if you fish and make a lot of repeated drifts, seems the " on /off" of the outboard better suited ? I'm not expert on diesels, but mostly they're started and only shut at end of day. Long runs.....the diesel.

Odor and fumes would likely be a bit more noticeable with the diesel.
Those 4 stroke 250 Yami's are so quiet, on friends boat we sometimes forget they're on.

As the guys who know these boats also report - ride with the diesel, inboard gasers, and then I/0's probably the best.
