New engines hitting transom.

So I got a pair of yam 150 to replace my 200 hpdi'
s. When I trim it up she hits the transome and did damage to the cover. I was thinking a 2" spacer of sorts would help and also keep my nose out of the water. Mounted on a bracket I have always had no reverse due to the wash hitting the bracket. A limit switch would help not hitting the transom. But my nose would still be sitting in the water. What is the rule of thumb for eng hight
and setback on a bracket ?

Yamaha has a trim limit module. Visit your local yamaha dealer.

Well.here is what I did. Cut 13"x 2" square tube. Drilled mounting holes and got longer bolts. Not pretty but it worked. The cover just hit but I thought it was 2 "" too close. An guessament.458095 Well 1" would of fixed it as I have a 1-1/2" gap at the transome. Till I run it I don't know if it's to high or lo

can't tell from the photo but, what are those two chromy looking things, where the bracket meets the transom?

In post above says 13in long 2in square tubing. Pretty much using it for 2 in spacer I think

I have a feeling that engine will crush the hollow tube in the rough. The spacers they sell are solid.

Yea might not happen first time but.. I would definitely buy some solid stainless or aluminum stock that tubing is going to crush and motors going to start bouncing around..
Or at least put solid spacers in the tube
Do you have plastic/lock nut washers on there can't tell from pic?

you would be better off playing it real safe and get 3 or 4 inch jack plates..... 2x2 tube is dangerous .
and having at an angle ( must have at angle for the bolt pattern) is even more dangerous.
with a small jack plate you can also raise it up a few and get better performance and clear everything...

I zoomed in on the picture, looks like the transducer cables coming thru the transom and turning down. Weird, looks like chrome fittings until you realy look close.

Kev, They actually look like Bennett trim tab tubing and on port side has a transducer cable tie wrap to it.

Update: I made a new dash and compleatly replaced every wire under the d458935[/ATTACHash. All new harness's and steering ram and tie bar. Tomorrow off to get painted. Teal with royal blue boot stripe. So next week will be splash day. Transducer and lenco tab wires.[ATTACH=CONFIG]458935

I have the motors mounted as high as I can get them and I am way to low in the water. Plus my lower sits 5" in the water when trimmed all the way up . So I ordered 2 cmc 65 jack plates. I'm hoping after they open the boat ramps I can put them on and get more rpms. It's topping out at 5000 rpms. Just got 11 hours on the motors . Hoping to get this worked out before my 20 hour service.[ATTACH=CONFIG]461672

Transducer wire.

[yachter55]

Yes

[roadkill636]

What length motas do you have? What transom length is your boat?

[yachter55]

Yes they are trim and tranducer wires. Adding 6" jack plates (cnc) changed center of gravity. Now with a full tank the swim platform is even with the water. 4 lead ingots helped raise it about a inch. Option A, welding a 1.5" solid plate on each side and get rid of the jack plates and lead. B) Or just add more lead.
