Mounting transducer near outdrive?

[salvageyard saviour]

Hope this isn't like an oil or efi topic, so here goes.

My Bennett trim tabs gives gives very little choice for a transom mount skimmer.
I want to put it between the outdrive and tab.

Also want to put temp/speed wheel somewhere. Maybe outside port tab like starboard stuff.

I've read trolling speed accuracy and prop slip could be negatives.

Drive collision with transducer and bubbles from prop would be first issue

A Mercruiser, I could see possibly a collision. This Electric shift is 8 inches from the transom and doesn't pivot from a gimbal or trim in. Transducer is 3 inches, can't see how they can make contact.

Do bubbles really have an impact at trolling speeds? This isn't thru hub exhaust.

Ayuh,..... I had oversized tabs on my ole fishin' barge,....

Had 2 sonars, with speed wheels,....
Mounted one on each side of the drive, in tight, like yer lookin' to do,...
No problem for many years,...
Though I did bust up a speed wheel, the day the ole girl was sinkin', 'n I beached it,.....

Thanks Bondo,
I read that when you replied to someone back in 2012 or 14 I think.

At trolling speeds, were you happy with the sonar quality?

Do you think the temp/speed wheel would be better on the port corner?
It would be more protected in close with the transducer.

Ayuh,.... If I wasn't Happy, I'd have changed it,.....

The speed wheel I crushed was part of the transducer, so I doubt it'll matter,....

You could also just get a shoot thru the hull transducer, mount it in the bilge (if not cored) and use a GPS unit for speed. Won't get water temp though.

Thanks for the reassurance
Agreed, doubt it'll matter and it'll be easier to route the cables from the same place.

I just got rid of all my older Impulse units, nice equipment but bulky. Can't even find those combo ducer/speedo on eBay anymore. Or the heads w/o Loran.

Thanks again
