Tsunami/bracket power options

[Jaizzen]

Bayou,


I have a 72 Tsunami with twin yamaha 150's (that easily push my boat on one motor 20kts), a full hardtop and a 150 gallon fuel tank. Sounds alot like what you are trying to do. I acually have mine transom mounted with no extra floatation. No issues in following or head seas. I did however raise the transom.

I dive and fish 100 miles off shore in it and run it in spearfishing tournaments loaded to the hilt and have no trouble with weight. I too am looking for newer power and have looked real hard at the DF140's. I just don't think they have the balls needed to get it done. The DF150's seem to be the best choice from everything that I can find. The E-techs are great lightweight motors, just pricey by comparison. I've recenetly considered a single DF300 with 30" shaft with a small 8hp 4sroke kicker mounted in the cabin. Is there anyone outthere running twin 150's 4 strokes on a Tsunami?

In addition, I would not push your fuel tank towards the transom to offset the weight of the hardtop. It's not necessary, secondly, if you put twins on your boat you will have plenty of weight aft. I actualy pushed my tank 8 inches forward and have been very happy with the results. I rarely use tabs even in seas. I keep reading about twins on a 23, but its mostly from the guys with Center consoles that don't take into account the amout of weight a Tsunami has forward. An apple to an orange in my opinion.

Looking forward to running into someone with a twin 4s setup. If not, I guess I'll be the first.

Best of luck.
