Q for rodbolt and other Yammy specialists

[scottoz]

I have a 21" seafarer deep v glass cruiser. She weighs about 1500kgs (approx 3,400 pounds) on the water when fuled up and no people in it. It currently runs a 115 2 stroke Yammie. It runs to 38miles per hour with 2 adults and 3 kids aboard. It runs to about 33 miles an hour with 4 adults 5 kids and a heap of gear. It planes quickly. I am keen to start using it offshore. To get there I have to cross a bar that is about 4.5 miles long 1.8 miles wide. I have not crossed in this boat before but from stationary in rough seas I can feel that she really hasnt got the grunt needed for safe consistent bar crossings.<br /><br />The transom is rated to 250hp (but that was power head rated so in modern terms thats, at a guess, about 200 hp. I wanted to got to around 175hp-200hp. I want to stay with Yammaha. I only use the boat about once a month on average. What would you suggest in terms of reliability and value. I like the idea of the 4 and 2 stroke HDPI' but I am concerned (not only of initial price) about expensive tech problems and maintance costs and whether the lack of very regular running will be a concern. Any feedback greatly appreciated.

well here on our side of the salt pond the only good one is the 150 with carbs. the 4 strokes seem to do well and the HPDI motors are rather maintenance heavy, as well as expensive sometimes.<br />you can still get either the 250 EFI or the 200 EFI both are decent and slightly less maint intensive. all the 2.6 and 3.1 EFI motors have a VST filter and O2 sensor that require maint. the 2.6 HPDI has the O2 sensor as well. the 3.3 HPDI motors do not have O2 sensors. <br /> myself, given the limited choices today, would opt for an F200 or an F225 if your static water line can handle the extra 150 pounds or so. but the EFI 2 stroke motors seem to do well.

Mate<br /><br />If you're getting 33 knots out of that motor on that boat you have plenty of power! I have the same donk (2001 Saltwater) on a 5.5m Quinnie Cuddy (800kg) and I'm hard pressed getting 35 knots with just me on board! This is a very responsive motor and works very well in bar crossings. I do 99% offshore in sometimes poor conditions and it is experience which gets me through this (and attention to safety detail) rather than having more power on the back. You have enough power to out run any swell. Save your money on hardware and do a bar-crossing course with the local VMR. The first thing they would suggest is 9 people is too many in flat water!

Thanks mate. Thats dead set - GPS confirmed on a number of occasions - but its miles per hour not knots! In knots 33 miles per hour is about 28.6 knots. What helps is it has no fine forfoot - just a straight 21 degrees stem to stern.<br /><br />Thanks for your assistance.

Re: Q for rodbolt and other Yammy specialists

Guys, I'm guessing Scott's problem with the motor is not outright speed, but the rate of acceleration due to having a 115 pushing almost two tonnes for his 21 footer as against 1 tonne for Whiteman's 18ft cuddy. So a repower would definitely make things a little more comfortable when a 6ft breaking wave is bearing down on you, however the idea of a bar-crossing course is a great piece of advice... I must enrol for one too!

You mentioned 38 mph with 2 adults/3 kids. I certainly wouldn't go near a bar-crossing with more people and I am loathe to take kids at all over a bar-crossing. To test, chuck the kids in the pool then chuck in their life jacket, turn on the pumps and see if they can get the jackets on! I'll bet they'll "go under". The VMR demonstrates this as part of the course.<br /><br />My kids can now do this as they were banned from fishing on the boat until they practiced it!

Thanks Whiteman - I would never take the kids accross the Bar - in fact they never go out in more than 5-10 knot winds on the Bay. I was using the weight example of the family in the boat as a reference point.<br /><br />Cheers
