 Bigger MotorI currently have a 25 Hp Vanguard motor on my longtail. Its a18'x60" riveted Jon. Can I unbolt the 25 and put a 35 Hp in it's place? Tired of boggin down with a full load. Or should I go with a SD?

Bigger Motor The 35 probably won't bolt right up without a little modification to the frame, more then likely you will have drill some new holes.

Re: Bigger Motor assuming it's a go-devil brand: I believe the prop shaft is 3/4in on the 25hp motor and 7/8 for the 35hp.
also when did vanguard make a 25hp motor I thought they where using koehler engines that were 25hp? _________________ 17*38 Klibert 23GDLT I toast to staying positive and testing negative! |

Re: Bigger Motor If in fact it is a big block 25 Vangaurd (which they make, just not sure if they ever put them on a MM) it will bolt right up with no modifications whatsoever.
If its a 25 Kohler its doable If its a 23 Briggs it'll be a chore. _________________ CSM Custom 18x42 Battleship with a 36 PD beating you to the hole My Rig (Old Motor) viewtopic.php?f=5&t=45193 (New Motor) viewtopic.php?f=5&t=54733 Stumps Fear Me |
