4 Stroke Weight Rephrased

[joe7670]

I started the 2/4 weight comparison, but I think I need to rephrase the question with the details below.

I have an 87 X-seadrive full transom Cuddy V. Tank is already moved up substantially at build.

Putting a bracket with swim platform. Can I get away with the 4 stroke Yamaha 150 weight at 478?

Is it a scenario where it's ok, borderline, or just not a good idea?

Will trim tabs be a nice option or a necessity?

I will not be mounting a kicker.

There is no bailing question cause it's not self bailing.

I'm like 1 call away from ordering this setup!
