Two Engines
Hi all.
Know there's been lots of talk about re-engine changing on our cats. But just wondered. I presently have a single 9.9 outboard and most people asume I would change to two 9.9 inboards. Why ? that would double my engine power . I would of thought two 6's or 8's would be more than enough and still more than my present. ??? Best regards

If you currently have Yamie 9.9 it is a high thrust o/b and the 6 & 8 are not.
The Yamie will stop you on your length, almost , and the others will do nothing. Dave

Tks for responding.
PM is about 3 - 3.5 tones. I just wondered why when replacing one engine (outboard) with two inboards every one seems to double up. using 6's ot 8's reduces the size quite a bit. Regds

Im not sure but it would be much heavier to add two 9 horse inboards. Go with the small ones. Outboards are much cheaper but diesel is a nice feature. I have a 30 hp outboard on my cat. I wouldn't put inboards in the boat as I feel it is too small. I would go with two 15's if I had to change.
Perhaps someone on the board knows of some very compact inboards that would suit your needs. |

They look cool. Check out the battery situation. You may need more range. Perhaps lots of solar power would help. |
