Another really well made video, enjoyed it! I only have a single engine bay boat. Have found the best method for me is to get on plane and trim up just until my revs start increasing and maybe back off a little. I guess the prop blades are getting closer to the surface at that point. My speed increases for the same RPM, trimmed up more than that is where it starts porpoising on flat water. Anyway, really just wanted to compliment you on your videos.
This is best video I have viewed that explains engine trim so thank you. For going in and out of Jupiter inlet can you run the four scenarios and how you would trim engine (e.g., outgoing tide, incoming wind, outgoing tide, outgoing wind, etc.). I’m still a lattice confused.
I can do that but as a generalization, when heading into the waves, you want your trim down to keep your bow down and into the waves. When going with the waves, you want your trim up to keep your bow up so you dont climb up a wave, fall off the wave and then pierce the next wave.
Yea, that’s part of what I am saying in this video how every boat is different. Bahama 41s don’t like a lot of trim until you get faster and get more hull out of the water. If I run up at 4400+ RPM that is where you start to see a giant performance difference between different trim settings and real increase in both speed and economy. I just used 4000 RPM as an easy constant.
In your case, if you increase RPM to compensate for the loss of speed with trim, then wouldn't the economy go back down? Maybe not much, but I guess each person's optimal setting will be different based on their preferences of performance, economy, bow height, etc.
No because quite the opposite happens. If you are running with my trim and you start trimming the motors up you will start to noticeably pick up speed, not lose speed. This is obviously up to a certain point until you are past optimum trim level and start losing performance.
Ehhh. Even with a head sea full trim down is still not always correct. It really is a case by case basis. With the right wave height and interval you can still spear a wave with full trim down. (Not commenting this as a call out saying you’re wrong. But instead so others that are still learning can know it’s not set in stone as to what you should be doing)
Believe me, I appreciate when people add context in the comments! So thank you! I am actually editing a video right now of a really rough crossing in a 34 SeaVee and I talk about exactly what you said how sometimes you need to keep the bow up a little bit and ignore the general rule of thumb
@@NickOlinde I’m 62 years old now but I can even remember back when I was 8 and driving my Dads boat. I remember raising the trim a little and feeling the hull release from the water and gaining 5 mph

I appreciate it man! I am here to try help as many boaters as I can. Let me know if there is anything in particular that you want to see.

I was kind of surprised about the knots decreasing as you trimmed up. I generally get a little more speed and better fuel economy as I trim up

Very informative and explained perfectly thank you cptn 👍🤘

Aha nvm you addressed later on it’s not an end all be all rule. I spoke too soon! :)

Hola un placer en ver tus vídeos tengo un bote Boston Whaler 35 outrage que quiero vender
Claro que si! Avísame si puedo ayudarte a venderlo, sería un placer ayudarte!
Thank you
My back yard.....saw Dragon Point in the video
A great place to live! I love Melbourne!
I can’t believe everyone doesn’t know all this. It common sense.
It’s scary to think there are captains that don’t know this
The lack of knowledge that the average boater has is alarming haha

@@davecindw It should be common sense, but sadly it is not!
Great info thank s
Any time!
